'Lord's' in the Bible

They mourned and wept and fasted until evening for Saul and Jonathan his son, and for the Lord’s people and the house of Israel, because they had fallen by the sword [in battle].

David said to him, “How is it that you were not afraid to put out your hand to destroy the Lord’s anointed?”

David said to the [fallen] man, “Your blood is on your own head, for your own mouth has testified against you, saying, ‘I have killed the Lord’s anointed.’”

Then the king told Zadok, “Take the ark of God back to [its rightful place in] the city [of Jerusalem, the capital]. If I find favor in the Lord’s sight, He will bring me back again and let me see both it and His dwelling place (habitation).

But Abishai the son of Zeruiah said, “Should not Shimei be put to death for this, because he cursed the Lord’s anointed?”

And David said to Abishai [his nephew], “Now Sheba the son of Bichri will do us more harm than Absalom did. Take your lord’s servants and pursue him, so that he does not find fortified cities for himself and escape from our sight.”

So David said to the Gibeonites, “What should I do for you? How can I make it good so that you will bless the Lord’s inheritance (Israel)?”

But the king spared Mephibosheth the son of Jonathan, the son of Saul, because of the Lord’s oath that was between David and Saul’s son Jonathan.
