'Necks' in the Bible

Now then, why are you testing God by putting a yoke on the disciples’ necks that neither our ancestors nor we have been able to bear?

Who have for my life laid down their own necks: unto whom not only I give thanks, but also all the churches of the Gentiles.

An unmarried woman or virgin is concerned about the affairs of the Lord, so that she may be holy in body and spirit. But a married woman is concerned about the affairs of this world, that is, about how she can please her husband. I'm saying this for your benefit, not to put a noose around your necks, but to promote good order and unhindered devotion to the Lord.
