Isaiah 50:2-5

2Why, when I came, was there no man? when I called, was there none to answer? Is my hand shortened at all, that it cannot redeem? or have I no power to deliver? behold, at my rebuke I dry up the sea, I make the rivers a wilderness: their fish stinketh, because there is no water, and dieth for thirst. 3I clothe the heavens with blackness, and I make sackcloth their covering.

4The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to him that is weary: he awakeneth morning by morning, he awakeneth my ear to hear as the learned. 5The Lord GOD opened my ear, and I was not rebellious, neither turned backward.
