'Shall' in the Bible

Iron and brass shall be thy bolts; And thy rest as thy days.

Thy refuge is the God of old, And underneath are the eternal arms; And he shall drive out the enemy from before thee, And shall say, Destroy them!

And Israel shall dwell in safety alone, The fountain of Jacob, in a land of corn and new wine; Also his heavens shall drop down dew.

Happy art thou, Israel! Who is like unto thee, a people saved by Jehovah, The shield of thy help, And the sword of thine excellency? And thine enemies shall come cringing to thee; And thou shalt tread upon their high places.
