'Unite' in the Bible

And thy brethren also, the tribe of Levi, the tribe of thy father, bring near with thee, that they may unite with thee, and minister unto thee; but thou and thy sons with thee shall serve before the tent of the testimony.

And they shall unite with thee, and keep the charge of the tent of meeting, for all the service of the tent; and no stranger shall come near to you.

Teach me thy way, Jehovah; I will walk in thy truth: unite my heart to fear thy name.
