'Joined' in the Bible

Then the Hebrews who had been with the Philistines for some time, and had gone up with them to their tents, turning round were joined to those who were with Saul and Jonathan.

Now after David's talk with Saul was ended, the soul of Jonathan was joined with the soul of David, and David became as dear to him as his very life.

And everyone who was in trouble, and everyone who was in debt, and everyone who was bitter in soul, came together to him, and he became captain over them: about four hundred men were joined to him.
