Adam Clarke on Numbers 24:9

He couched, he lay down as a lion, etc. - See the original terms explained Num 23:24 (note).

These oracles, delivered by Balaam, are evident prophecies of the victories which the Israelites should gain over their enemies, and of their firm possession of the promised land. They may also refer to the great victories to be obtained by the Lord Jesus Christ, that Lion of the tribe of Judah, over sin, death, and Satan, the grand enemies of the human race; and to that most numerous posterity of spiritual children which should be begotten by the preaching of the Gospel.
