John Gill Commentary 1 Samuel 10:18

"and he said unto the children of Israel, Thus saith Jehovah, the God of Israel, I brought up Israel out of Egypt, and I delivered you out of the hand of the Egyptians, and out of the hand of all the kingdoms that oppressed you:" — 1 Samuel 10:18 (ASV)

And said unto the children of Israel
In the name of the Lord, using the phrase which the prophets used when they spoke in the name of the Lord:

thus says the Lord God of Israel ;
the great Jehovah, the Being of beings, the covenant God of his people Israel:

I brought up Israel out of Egypt ;
when in bondage there, with a mighty hand and outstretched arm, by means of signs and wonders done by the hands of Moses and Aaron; the Lord working mightily with them, and thereby inclining Pharaoh and his people to let them go:

and delivered you out of the hand of the Egyptians ;
at the Red sea, drowning them in it, when they threatened Israel with an utter destruction:

and out of the hand of all kingdoms, [and] of them that oppressed you ;
as the Arabic writers, the kingdoms of Og and Bashan in their way to Canaan, and the Mesopotamians, Moabites, Canaanites, Midianites, Ammonites, and Philistines, in the times of the judges; all which is observed to show their ingratitude, and aggravate their guilt.
