God brought them out of Egypt. — Literally, is bringing them. The use of the participle denotes the continuance of the action. He who brought them forth out of Egypt was still conducting them on their march. There is an obvious allusion in these words to those of Balak in Numbers 22:5 : “Behold, there is a people come out from Egypt.” Seeing that the people did not come out of Egypt in obedience to their own caprice, but under Divine guidance, it was vain for Balak to resist them on their course, seeing that to contend with them was to contend against God.
The strength of an unicorn. — Better, of a buffalo. (Comp. Deuteronomy 33:17 — a passage closely resembling the present — from which it appears that the reem had more than one horn.)
