'Lord God of Israel' in the Bible

He said to the Israelites, "This is what the Lord God of Israel says, 'I brought Israel up from Egypt and I delivered you from the power of the Egyptians and from the power of all the kingdoms that oppressed you.

Then Saul said, "O Lord God of Israel! If this sin has been committed by me or by my son Jonathan, then, O Lord God of Israel, respond with Urim. But if this sin has been committed by your people Israel, respond with Thummim." Then Jonathan and Saul were indicated by lot, while the army was exonerated.

Jonathan said to David, "The Lord God of Israel is my witness. I will feel out my father about this time the day after tomorrow. If he is favorably inclined toward David, will I not then send word to you and let you know?

Then David said, "O Lord God of Israel, your servant has clearly heard that Saul is planning to come to Keilah to destroy the city because of me.

Will the leaders of Keilah deliver me into his hand? Will Saul come down as your servant has heard? O Lord God of Israel, please inform your servant!" Then the Lord said, "He will come down."
