'Joint' in the Bible

And if children, heirs also: heirs of God, and Christ's joint heirs; if indeed we suffer with him, that we may also be glorified with him.

that they who are of the nations should be joint heirs, and a joint body, and joint partakers of his promise in Christ Jesus by the glad tidings;

from whom the whole body, fitted together, and connected by every joint of supply, according to the working in its measure of each one part, works for itself the increase of the body to its self-building up in love.
