3 Bible Verses about Necks

Stiff necked, and uncircumcised in heart and ears, you always fight against the Holy Spirit; as your fathers did, you also do.

but whoever offends one of these little ones that believe in me, it would be better for him that a millstone should be hung to his neck, and that he should be plunged into the depths of the sea.

And whoever shall offend one of the little ones having faith, it would be better for him if a millstone was put about his neck and he was cast into the sea.
