'Lord's' in the Bible

Then the children of Israel again did evil in the eyes of the Lord; and the Lord made Eglon, king of Moab, strong against Israel, because they had done evil in the Lord's eyes.

Then the chiefs went down to the doors; the Lord's people went down among the strong ones.

So they put away the strange gods from among them, and became the Lord's servants; and his soul was angry because of the sorrows of Israel.

Then whoever comes out from the door of my house, meeting me when I come back in peace from the children of Ammon, will be the Lord's and I will give him as a burned offering.
