'I Am the Lord' in the Bible

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.

I will give them a heart to know Me, [understanding fully] that I am the Lord; and they will be My people, and I will be their God, for they will return to Me with their whole heart.

“Behold, I am the Lord, the God of all flesh; is there anything too difficult for Me?”
