'Uniting' in the Bible

And the Lord said to Moses, Now you are going to rest with your fathers; and this people will be false to me, uniting themselves to the strange gods of the land where they are going; they will be turned away from me and will not keep the agreement I have made with them.

And not for that nation only, but for the purpose of uniting in one body the children of God all over the world.

If then there is any comfort in Christ, any help given by love, any uniting of hearts in the Spirit, any loving mercies and pity,

Through him uniting all things with himself, having made peace through the blood of his cross; through him, I say, uniting all things which are on earth or in heaven.
