'Lord's' in the Bible

Though you seem to soar like an eagleand make your nest among the stars,even from there I will bring you down.This is the Lord’s declaration.

In that day—this is the Lord’s declaration—will I not eliminate the wise ones of Edomand those who understandfrom the hill country of Esau?

And saviours shall come up on mount Zion to judge the mount of Esau; and the kingdom shall be the LORD'S.
