'Shall' in the Bible

A bundle of myrrh is my wellbeloved unto me; he shall lie all night betwixt my breasts.

I have put off my coat; how shall I put it on? I have washed my feet; how shall I defile them?

I said, I will go up to the palm tree, I will take hold of the boughs thereof: now also thy breasts shall be as clusters of the vine, and the smell of thy nose like apples;

We have a little sister, and she hath no breasts: what shall we do for our sister in the day when she shall be spoken for?
