If one acts as a historian or Biblical scholar and views the Old Testament prophets analytically, one can conclude that all the prophets spoke, in a way, as evangelists. Three powerful examples:
ISAIAH 53: 1 Who has believed what we have heard? And to whom has the arm of the LORD been revealed? 2 For he grew up before him like a young plant, and like a root out of dry ground; he had no form or comeliness that we should look at him, and no beauty that we should desire him. 3 He was despised and rejected by men; a man of sorrows, and acquainted with grief; and as one from whom men hide their faces he was despised, and we esteemed him not. 4 Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God,and afflicted .5 But he was wounded for our transgressions, he was bruised for our iniquities; upon him was the chastisement that made us whole, and with his stripes we are healed. 6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD has laid on him the iniquity of us all. 7 He was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter, and like a sheep that before its shearers is dumb, so he opened not his mouth .8 By oppression and judgment he was taken away; and as for his generation, who considered that he was cut off out of the land of the living, stricken for the transgression of my people? 9 And they made his grave with the wicked and with a rich man in his death, although he had done no violence, and there was no deceit in his mouth. 10 Yet it was the will of the LORD to bruise him; he has put him to grief; when he makes himself an offering for sin, he shall see his offspring, he shall prolong his days; the will of the LORD shall prosper in his hand; 11 he shall see the fruit of the travail of his soul and be satisfied; by his knowledge shall the righteous one, my servant, make many to be accounted righteous; and he shall bear their iniquities. 12 Therefore I will divide him a portion with the great, and he shall divide the spoil with the strong; because he poured out his soul to death, and was numbered with the transgressors; yet he bore the sin of many, and made intercession for the transgressors.
Psalm 22:1 My God, my God, why hast thou forsaken me? Why art thou so far from helping me, from the words of my groaning? 2 O my God, I cry by day, but thou dost not answer; and by night, but find no rest. 3 Yet thou art holy, enthroned on the praises of Israel. 4 In thee our fathers trusted; they trusted, and thou didst deliver them .5 To thee they cried, and were saved; in thee they trusted, and were not disappointed. 6 But I am a worm, and no man; scorned by men, and despised by the people. 7 All who see me mock at me, they make mouths at me, they wag their heads; 8 “He committed his cause to the LORD; let him deliver him, let him rescue him, for he delights in him!” 9 Yet thou art he who took me from the womb; thou didst keep me safe upon my mother’s breasts. 10 Upon thee was I cast from my birth, and since my mother bore me thou hast been my God. 11 Be not far from me, for trouble is near and there is none to help. 12 Many bulls encompass me, strong bulls of Bashan surround me; 13 they open wide their mouths at me, like a ravening and roaring lion. 14 I am poured out like water, and all my bones are out of joint; my heart is like wax, it is melted within my breast; 15 my strength is dried up like a potsherd, and my tongue cleaves to my jaws; thou dost lay me in the dust of death .16 Yea, dogs are round about me; a company of evildoers encircle me; they have pierced my hands and feet –17 I can count all my bones — they stare and gloat over me; 18 they divide my garments among them, and for my raiment they cast lots . 19 But thou, O LORD, be not far off! O thou my help, hasten to my aid! 20 Deliver my soul from the sword, my life from the power of the dog! 21 Save me from the mouth of the lion, my afflicted soul from the horns of the wild oxen! 22 I will tell of thy name to my brethren; in the midst of the congregation I will praise thee: 23 You who fear the LORD, praise him! all you sons of Jacob, glorify him, and stand in awe of him, all you sons of Israel! 24 For he has not despised or abhorred the affliction of the afflicted; and he has not hid his face from him, but has heard, when he cried to him. 25 From thee comes my praise in the great congregation; my vows I will pay before those who fear him. 26 The afflicted shall eat and be satisfied; those who seek him shall praise the LORD! May your hearts live for ever! 27 All the ends of the earth shall remember and turn to the LORD; and all the families of the nations shall worship before him. 28 For dominion belongs to the LORD, and he rules over the nations. 29 Yea, to him shall all the proud of the earth bow down; before him shall bow all who go down to the dust, and he who cannot keep himself alive. 30 Posterity shall serve him; men shall tell of the Lord to the coming generation…
Psalm 69:1 Save me, O God! For the waters have come up to my neck.2 I sink in deep mire, where there is no foothold; I have come into deep waters, and the flood sweeps over me. 3 I am weary with my crying; my throat is parched. My eyes grow dim with waiting for my God. 4 More in number than the hairs of my head are those who hate me without cause; mighty are those who would destroy me, those who attack me with lies. What I did not steal must I now restore? 5 O God, thou knowest my folly; the wrongs I have done are not hidden from thee. 6 Let not those who hope in thee be put to shame through me, O Lord GOD of hosts; let not those who seek thee be brought to dishonor through me, O God of Israel. 7 For it is for thy sake that I have borne reproach, that shame has covered my face. 8 I have become a stranger to my brethren, an alien to my mother’s sons. 9 For zeal for thy house has consumed me, and the insults of those who insult thee have fallen on me.10 When I humbled my soul with fasting, it became my reproach. 11 When I made sackcloth my clothing, I became a byword to them. 12 I am the talk of those who sit in the gate, and the drunkards make songs about me. 13 But as for me, my prayer is to thee, O LORD. At an acceptable time, O God, in the abundance of thy steadfast love answer me. With thy faithful help 14 rescue me from sinking in the mire; let me be delivered from my enemies and from the deep waters. 15 Let not the flood sweep over me, or the deep swallow me up, or the pit close its mouth over me. 16 Answer me, O LORD, for thy steadfast love is good; according to thy abundant mercy, turn to me. 17 Hide not thy face from thy servant; for I am in distress, make haste to answer me. 18 Draw near to me, redeem me, set me free because of my enemies! 19 Thou knowest my reproach, and my shame and my dishonor; my foes are all known to thee. 20 Insults have broken my heart, so that I am in despair. I looked for pity, but there was none; and for comforters, but I found none. 21 They gave me poison for food, and for my thirst they gave me vinegar to drink. 22 Let their own table before them become a snare; let their sacrificial feasts be a trap. 23 Let their eyes be darkened, so that they cannot see; and make their loins tremble continually. 24 Pour out thy indignation upon them, and let thy burning anger overtake them. 25 May their camp be a desolation, let no one dwell in their tents. 26 For they persecute him whom thou hast smitten, and him whom thou hast wounded, they afflict still more. 27 Add to them punishment upon punishment; may they have no acquittal from thee. 28 Let them be blotted out of the book of the living; let them not be enrolled among the righteous. 29 But I am afflicted and in pain; let thy salvation, O God, set me on high! 30 I will praise the name of God with a song; I will magnify him with thanksgiving. 31 This will please the LORD more than an ox or a bull with horns and hoofs. 32 Let the oppressed see it and be glad; you who seek God, let your hearts revive. 33 For the LORD hears the needy, and does not despise his own that are in bonds. 34 Let heaven and earth praise him, the seas and everything that moves therein. 35 For God will save Zion and rebuild the cities of Judah; and his servants shall dwell there and possess it; 36 the children of his servants shall inherit it, and those who love his name shall dwell in it.
