Cursed [shalt] thou [be] when thou comest in, and cursed [shalt] thou [be] when thou goest out. ] (See Gill on Deuteronomy 28:6). (See Gill on Deuteronomy 28:16).
20
The LORD will send curses on you. You won't know what's going on. In everything you do, he will be angry with you. You will be destroyed suddenly and completely. That will happen because you did an evil thing when you deserted the LORD.
21
He will send all kinds of sicknesses on you. He'll send them until he has destroyed you. He'll remove you from the land you are entering to take as your own.
