8 yet now make an agreement with my lord the king of the Assyrians, and I will give you two thousand horses, if ye shall be able to set riders upon them.

Esias 36:8 In-Context

6 Behold, thou trustest on this bruised staff of reed, on Egypt: as a man leans upon it, it shall go into his hand, and pierce it: so is Pharao king of Egypt and all that trust in him.
7 But if ye say, We trust in the Lord our God;
8 yet now make an agreement with my lord the king of the Assyrians, and I will give you two thousand horses, if ye shall be able to set riders upon them.
9 And how can ye turn to the face of the satraps? They that trust on the Egyptians for horse and rider, are servants.
10 And now, Have we come up against this land to fight against it without the Lord? The Lord said to me, Go up against this land, and destroy it.
