John Gill Commentary 2 Kings 10:32

"In those days Jehovah began to cut off from Israel: and Hazael smote them in all the borders of Israel;" — 2 Kings 10:32 (ASV)

In those days the Lord began to cut Israel short
To bring their dominions into a narrower compass; this was done in the days of Jehu, though he was so active and courageous, wherefore the hand of God was the more seen in it:

and Hazael smote them in all the coasts of Israel ;
which bordered on his country, when he did what Elisha foretold he would, (2 Kings 8:12) .
