'Lord's' in the Bible

Now concerning the virgins [of marriageable age] I have no command of the Lord, but I give my opinion as one who by the Lord’s mercy is trustworthy.

Have we not the right to take along with us a believing wife, as do the rest of the apostles and the Lord’s brothers and Cephas (Peter)?

Is the cup of blessing which we bless [at the Lord’s Supper] not a sharing in the blood of Christ? [Indeed it is.] Is the bread which we break not a sharing in the body of Christ? [Indeed it is.]

You cannot drink [both] the Lord’s cup and the cup of demons. You cannot share in both the Lord’s table and the table of demons [thereby becoming partners with them].

For the [whole] earth is the Lord’s, and everything that is in it.

For every time you eat this bread and drink this cup, you are [symbolically] proclaiming [the fact of] the Lord’s death until He comes [again].

So then, my brothers and sisters, when you come together to eat [the Lord’s Supper], wait for one another [and see to it that no one is left out].

If Timothy comes, see to it that [you put him at ease, so that] he has nothing to fear in regard to you, for he is [devotedly] doing the Lord’s work, just as I am.
