Isaiah 31:1

Woe to them that put their trust in the horses and chariots of Egypt! The Jews were painfully conscious of their weakness in cavalry as compared with the Assyrians, and this was one of the considerations that made a league with Egypt so attractive in their eyes (see ch. Isaiah 30:16; Isaiah 36:8-9). Egypt was always renowned in antiquity for its strength in this arm (Hom. Iliadix. 383; Diodorus, i. 45). To the prophets horses and chariots were in themselves objectionable as embodiments of irreligious militarism (cf. ch. Isaiah 2:7); they were of course doubly so when obtained through compacts with foreign states.

neither seek the Lord i.e. seek His counsel (Isaiah 30:2).
