'God of Israel' in the Bible

Afterward Moses and Aaron came, and said to Pharaoh, "This is what the LORD, the God of Israel, says, 'Let my people go, that they may hold a feast to me in the wilderness.'"

They saw the God of Israel. Under his feet was like a paved work of sapphire stone, like the skies for clearness.

He said to them, "Thus says the LORD, the God of Israel, 'Every man put his sword on his thigh, and go back and forth from gate to gate throughout the camp, and every man kill his brother, and every man his companion, and every man his neighbor.'"

Three times in the year all your males shall appear before the Lord GOD, the God of Israel.
