Matthew Poole and continuators on Numbers 23:22

22 God brought them out of Egypt : he hath as it were the strength of an unicorn .

To wit, by a strong hand and in spight of all their enemies, and therefore it is in vain to seek or hope to overcome them.

Either 1. God, last mentioned. But so the comparison is mean and unbecoming. Or rather 2. Israel, whom God brought out of Egypt, such change of numbers being very common in the Hebrew language. The sence is, Israel is not now, what he was in Egypt, a poor, weak, dispirited, unarmed people, but high and strong and invincible.

Whose great strength and fierceness is celebrated in Scripture, Numb. 24. 8. Deut. 33. 17. Iob 39. 9. Psal. 22. 21. and 92. 10. But whether it be an Unicorn, or a Rhinoceros, or a strong and fierce kind of wild goat, which is here called reem, it is not needful here to determine.
