'Shalt' in the Bible

Remember therefore whence thou art fallen, and repent, and do the first works: but if not, I am coming to thee, and I will remove thy lamp out of its place, except thou shalt repent.

Remember therefore how thou hast received and heard, and keep it and repent. If therefore thou shalt not watch, I will come upon thee as a thief, and thou shalt not know at what hour I shall come upon thee.
