'Joined' in the Bible

And the Philistines put themselves in array against Israel: and when they joined battle, Israel was smitten before the Philistines: and they slew of the army in the field about four thousand men.

There were Hebrews from the area who had gone earlier into the camp to join the Philistines, but even they joined the Israelites who were with Saul and Jonathan.

When all the Israelite men who had been hiding in the hill country of Ephraim heard that the Philistines were fleeing, they also joined Saul and Jonathan in the battle.

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.

So David left Gath and took refuge in the cave of Adullam. When David’s brothers and his father’s whole family heard, they went down and joined him there.

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.
