'United' in the Bible

O my soul, come not thou into their council; Unto their assembly, my glory, be not thou united; For in their anger they slew a man, And in their self-will they hocked an ox.

For if we have become united with him in the likeness of his death, we shall be also in the likeness of his resurrection;

For indeed we have had good tidings preached unto us, even as also they: but the word of hearing did not profit them, because it was not united by faith with them that heard.
