'Unity' in the Bible

{A Song of degrees of David.} Behold, how good and how pleasant it is for brethren to dwell together in unity!

"Will a couple walk in unity without having met?

And I shepherded the flock [doomed] to slaughter, even the afflicted of the flock. I took two staffs, one I called Kindness, and the other I called Unity, and I shepherded the flock.

And I cut asunder my second staff, Bands, to break the unity between Judah and Israel.

I in them and You in Me, that they may be perfected in unity, so that the world may know that You sent Me, and loved them, even as You have loved Me.

Now may the God of endurance and comfort give you unity with one another in accordance with Christ Jesus,

For just as the body is one and yet has many parts, and all the parts, though many, form [only] one body, so it is with Christ.

Grace to you and peace [inner calm and spiritual well-being] from God our Father and the Lord Jesus Christ.

For He Himself is our peace and our bond of unity. He who made both groups—[Jews and Gentiles]—into one body and broke down the barrier, the dividing wall [of spiritual antagonism between us],

Endeavouring to keep the unity of the Spirit in the bond of peace.

Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:

Above all, put on love—the perfect bond of unity.
