'Lord God of Israel' in the Bible

Then David said, “Lord God of Israel, Your servant has heard that Saul intends to come to Keilah and destroy the town because of me.

Will the citizens of Keilah hand me over to him? Will Saul come down as Your servant has heard? Lord God of Israel, please tell Your servant.”The Lord answered, “He will come down.”

Then David said to Abigail, “Praise to the Lord God of Israel, who sent you to meet me today!

Otherwise, as surely as the Lord God of Israel lives, who prevented me from harming you, if you had not come quickly to meet me, Nabal wouldn’t have had any men left by morning light.”
