'Lord's' in the Bible

This is the Lord's message that was given to Joel the son of Pethuel:

The meat offering and the drink offering is cut off from the house of the LORD; the priests, the LORD'S ministers, mourn.

Even now—this is the Lord’s declaration—turn to Me with all your heart,with fasting, weeping, and mourning.

Let the priests, the Lord’s ministers,weep between the portico and the altar.Let them say:“Have pity on Your people, Lord,and do not make Your inheritance a disgrace,an object of scorn among the nations.Why should it be said among the peoples,‘Where is their God?’”

In that daythe mountains will drip with sweet wine,and the hills will flow with milk.All the streams of Judah will flow with water,and a spring will issue from the Lord’s house,watering the Valley of Acacias.
