'Know the Lord' in the Bible

I will even betroth you to me in faithfulness; and you shall know the LORD.

Their deeds won't allow them to turn to their God; for the spirit of prostitution is within them, and they do not know the LORD.

Let us acknowledge the LORD. Let us press on to know the LORD. As surely as the sun rises, The LORD will appear. He will come to us like the rain, like the spring rain that waters the earth."
