Verse 39. Would not obey, etc. This refers to what they said of him when he was in the mount, Ex 32:1,23.

In their hearts turned, etc. They wished to return to Egypt. They regretted that they had come out of Egypt, and desired again the things which they had there, as preferable to what they had in the desert, Nu 11:5. Perhaps, however, the expression means, not that they desired literally to return to Egypt, but that their hearts inclined to the habits and morals of the Egyptians. They forsook God, and imitated the idolatries of the Egyptians.
