A thought: why do we always think of prophets are really old? They started out young. Here is Raphael's Isaiah.
God will hear the cry of the poor, be assured, little "puny mites" as one translation states.
Isaiah 41:13-29
Douay-Rheims
13 For I am the Lord thy God, who take thee by the hand, and say to thee: Fear not, I have helped thee.
14 Fear not, thou worm of Jacob, you that are dead of Israel: I have helped thee, saith the Lord: and thy Redeemer the Holy One of Israel.
15 I have made thee as a new thrashing wain, with teeth like a saw: thou shall thrash the mountains, and break them in pieces: and shalt make the hills as chaff.
16 Thou shalt fan them, and the wind shall carry them away, and the whirlwind shall scatter them: and thou shalt rejoice in the Lord, in the Holy One of Israel thou shalt be joyful.
17 The needy and the poor seek for waters, and there are none: their tongue hath been dry with thirst. I the Lord will hear them, I the God of Israel will not forsake them.
18 I will open rivers in the high bills, and fountains in the midst of the plains: I will turn the desert into pools of waters, and the impassable land into streams of waters.
19 I will plant in the wilderness the cedar, and the thorn, and the myrtle, and the olive tree: I will set in the desert the fir tree, the elm, and the box tree together:
20 That they may see and know, and consider, and understand together that the hand of the Lord hath done this, and the Holy One of Israel hath created it.
21 Bring your cause near, saith the Lord: bring hither, if you have any thing to allege, saith the King of Jacob.
22 Let them come, and tell us all things that are to come: tell us the former things what they were: and we will set our heart upon them, and shall know the latter end of them, and tell us the things that are to come.
23 shew the things that are to come hereafter, and we shall know that ye are gods. Do ye also good or evil, if you can: and let us speak, and see together.
24 Behold, you are of nothing, and your work of that which hath no being: he that hath chosen you is an abomination.
25 I have raised up one from the north, and he shall come from the rising of the sun: he shall call upon my name, and he shall make princes to be as dirt, and as the potter treading clay.
26 Who hath declared from the beginning, that we may know: and from time of old, that we may say: Thou art just. There is none that sheweth, nor that foretelleth, nor that heareth your words.
27 The first shall say to Sion: Behold they are here, and to Jerusalem I will give an evangelist.
28 And I saw, and there was no one even among them to consult, or who, when I asked, could answer a word.
