'Know' in the Bible

or when he touches human uncleanness with regard to anything by which he can become unclean, even if he did not realize it, but he himself has later come to know it and is guilty;

or when a person swears an oath, speaking thoughtlessly with his lips, whether to do evil or to do good, with regard to anything which the individual might speak thoughtlessly in an oath, even if he did not realize it, but he himself has later come to know it and is guilty with regard to one of these oaths --

"If a person sins and violates any of the Lord's commandments which must not be violated (although he did not know it at the time, but later realizes he is guilty), then he will bear his punishment for iniquity

so that your future generations may know that I made the Israelites live in temporary shelters when I brought them out from the land of Egypt. I am the Lord your God.'"
