Isaiah 49:4

Then I said By way of objection; I have laboured in vain Lord, thou sayest thou wilt be glorified by my ministry; but I find it otherwise. I have spent my strength for naught Without any considerable fruit of my word and works. “The words,” says Vitringa, “contain the complaint of the Son of God, concerning the small fruit of his mission to the Jews, and the small hope of establishing and successfully propagating his kingdom among them; like that which is attributed to the same great Teacher and his apostles, Isaiah 53:1. But at the same time he supports himself with the hope, that he should obtain a glorious and abundant fruit of his divine mission in the world; for that his judgment, or right, was with God, and the reward of his work laid up with him; who would take good care, according to his wisdom and justice, that the proper and full recompense of his labour should be paid him.” According to this just exposition of the passage, the latter clause of the verse agrees with the former, and the sense of both is briefly this: Though I see little or no fruit of my labour among the Jews, and meet with nothing but contempt, and reproach, and ill usage from them; yet God sees my fidelity and diligence in my work, and he will give judgment for me, and amply reward me in due time.
