'Know the Lord' in the Bible

Then I said, "These are only the poor, they're foolish, for they don't know the LORD's way, the requirement of their God.

Let me go to the leaders and speak to them. For they know the LORD's way, the requirement of their God." "But they, all together, have broken the yoke and torn off the restraints.

No longer will a person teach his neighbor or his relative: "Know the LORD.' Instead, they'll all know me, from the least to the greatest of them," declares the LORD. "Indeed, I'll forgive their iniquity, and I'll remember their sin no more."
