Now therefore make confession to the Lord God of your fathers,
&c.] Of their sin, and express their detestation of it, and repentance for it:
and do his pleasure;
obey his will, and particularly in this case:
and separate yourselves from the people of the land;
the Canaanites, &c. have no fellowship with them, make no covenants, contracts, and alliances with them for the future;
and from the strange wives;
they had taken; put them away.
