[Ali Imran]

The phrase "I will bless those who bless you" is found in Genesis 12:3. This verse is part of God's promise to Abraham, where He states that He will bless those who show favor to Abraham, and curse those who oppose him. 

The full verse reads: "I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed"

Jeremiah 8:8 said there were scribes who have falsified the scriptures. So we cannot trust the Bible.
