'To the Lord' in the Bible

He that regardeth the day, regardeth it to the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord; for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.

For none of us liveth to himself, and none dieth to himself. But if we live, we live unto the Lord; and if we die, we die unto the Lord.
