'Know' in the Bible

“Therefore I was angry with this generation,And said, ‘They always go astray in their heart,And they did not know My ways’;

“And they shall not teach everyone his fellow citizen,And everyone his brother, saying, ‘Know the Lord,’For all will know Me,From the least to the greatest of them.

For we know Him who said, “Vengeance is Mine, I will repay.” And again, “The Lord will judge His people.”

For you know that even afterwards, when he desired to inherit the blessing, he was rejected, for he found no place for repentance, though he sought for it with tears.
