'Knows' in the Bible

“Even the stork in the skyKnows her seasons [of migration],And the turtledove, the swallow and the craneObserve the time of their return.But My people do not knowThe law of the Lord.

but let the one who boasts boast in this, that he understands and knows Me [and acknowledges Me and honors Me as God and recognizes without any doubt], that I am the Lord who practices lovingkindness, justice and righteousness on the earth, for in these things I delight,” says the Lord.

because they have acted foolishly in Israel and have committed adultery with their neighbors’ wives and in My Name have spoken false and concocted words, which I did not command them. I am He who knows and I am a witness,” says the Lord.’”
