O my people, remember now what Balak king of Moab consulted, and what Balaam the son of Beor answered him from Shittim unto Gilgal; that ye may know the righteousness of the LORD. Remember now what Balak king of Moab consulted - He sent for Balaam to curse your fathers; but by my influence he was obliged to bless them. See Numbers 22 (note) and Numbers 23 (note), and the notes there, where this subject is largely considered.
From Shittim unto Gilgal - From the encampment at Shittim, Numbers 25:1, on the way to that of Gilgal, Joshua 4:19. Balaam gave different answers in the interval between these places. We may suppose that the encampments of Israel advanced slowly to that part of Jordan which was opposite to Gilgal. The Chaldee has, "Were there not wonderful things done in your behalf from the valley of Shittim to the house of Gilgal?" See Joshua 3:1; Joshua 4:20. Thus there will be a reference to the miraculous passage over Jordan. See Newcome.
That ye may know the righteousness - The just, equitable, and merciful dealing of the Most High. Recollect those things, that ye may have a proper impression of this. There are many interpretations given of this rather obscure clause; what I have proposed seems to me the most simple.
This is the sum of the address; and here the case of the plaintiff terminates, the prisoners being called to show why the sentence of the law should not be pronounced. I make no apology for using any forensic terms, as the passages before us refer to a case brought into a court to be judged, and the terms in the original are all such as are proper for a court of justice; and the thing itself is called the Lord's controversy, ריב יהוה rib Yehovah, Jehovah's suit at law. And hence it is said, He will plead, litigate, with Israel.
