'Knit' in the Bible

So all the men of Israel were gathered against the city, knit together as one man.

And it came to pass, when he had made an end of speaking unto Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul.

And David went out to meet them, and answered and said unto them, If ye be come peaceably unto me to help me, mine heart shall be knit unto you: but if ye be come to betray me to mine enemies, seeing there is no wrong in mine hands, the God of our fathers look thereon, and rebuke it.
