John Gill Commentary Numbers 32:14

"And, behold, ye are risen up in your fathers` stead, an increase of sinful men, to augment yet the fierce anger of Jehovah toward Israel." — Numbers 32:14 (ASV)

And, behold, you are risen up in your fathers' stead
Succeeded them in their families, of which they were now the heads; and in their substance, their flocks, and herds; and he suggests also, in their manners amid evil dispositions:

an increase of sinful men ;
this new generation was greatly increased, for when the number was taken, as it was but a little before this time, they were pretty near the same number as of those that came out of Egypt; but then they were not only an increase of men, but of sinful men, like fathers like sons:

to augment yet the fierce anger of the Lord toward Israel ;
to make it greater and fiercer towards that nation than even their fathers had by their many sins and transgressions.
