'Cannot' in the Bible

Moreover, your little ones whom you said would become prey, and your sons, who today have no knowledge of good or evil, shall enter Canaan, and I will give it to them and they shall possess it.

“The Lord will strike you with the boils of Egypt and with tumors and with the scab and the itch that you cannot heal.

The Lord will strike you on the knees and on the legs with sore boils that you cannot heal, from the sole of your foot to the crown of your head.
