'Lord's' in the Bible

For he who was called in the Lord being a bondservant is the Lord's free man. Likewise he who was called being free is Christ's bondservant.

for "the earth is the Lord's, and its fullness."

But if anyone says to you, "This was offered to idols," don't eat it for the sake of the one who told you, and for the sake of conscience. For "the earth is the Lord's, and all its fullness."

When therefore you assemble yourselves together, it is not the Lord's supper that you eat.

For as often as you eat this bread and drink this cup, you proclaim the Lord's death until he comes.

Therefore whoever eats this bread or drinks the Lord's cup in a way unworthy of the Lord will be guilty of the body and the blood of the Lord.

For he who eats and drinks in an unworthy way eats and drinks judgment to himself, if he doesn't discern the Lord's body.

Therefore, my beloved brothers, be steadfast, immovable, always abounding in the Lord's work, because you know that your labor is not in vain in the Lord.
