'To the Lord' in the Bible

He who keeps the day, keeps it to the Lord; and he who takes food, takes it as to the Lord, for he gives praise to God; and he who does not take food, to the Lord he takes it not, and gives praise to God.

As long as we have life we are living to the Lord; or if we give up our life it is to the Lord; so if we are living, or if our life comes to an end, we are the Lord's.

And again, Give praise to the Lord, all you Gentiles; and let all the nations give praise to him.
