'God of Israel' in the Bible

And afterward Moses and Aaron came and said to Pharaoh, “Thus says the Lord, the God of Israel, ‘Let My people go that they may celebrate a feast to Me in the wilderness.’”

and they saw the God of Israel; and under His feet there appeared to be a pavement of sapphire, as clear as the sky itself.

He said to them, “Thus says the Lord, the God of Israel, ‘Every man of you put his sword upon his thigh, and go back and forth from gate to gate in the camp, and kill every man his brother, and every man his friend, and every man his neighbor.’”

Three times a year all your males are to appear before the Lord God, the God of Israel.
