'Lord God of Israel' in the Bible

and said to them, “You are the heads of the fathers’ households of the Levites; consecrate yourselves both you and your relatives, that you may bring up the ark of the Lord God of Israel to the place that I have prepared for it.

So the priests and the Levites consecrated themselves to bring up the ark of the Lord God of Israel.

He appointed some of the Levites as ministers before the ark of the Lord, even to celebrate and to thank and praise the Lord God of Israel:

Then he called for his son Solomon, and charged him to build a house for the Lord God of Israel.

For David said, “The Lord God of Israel has given rest to His people, and He dwells in Jerusalem forever.

These were their offices for their ministry when they came in to the house of the Lord according to the ordinance given to them through Aaron their father, just as the Lord God of Israel had commanded him.

So David blessed the Lord in the sight of all the assembly; and David said, “Blessed are You, O Lord God of Israel our father, forever and ever.
