This "real children of Israel" is baked in Black Israelite idealogy and it's cultural erasure of Jewish history, of course what makes this even worse is that he thinks its a good idea to quote Hitler as someone speaking the truth and its spreading antisemitic thought that Jews are an insidious force that is controlling things and wants to dominate the world, such conspiracy theories have motivated violent action against Jewish people in the past. A friend of mine and I were talking about it and I don't want to get too deep into implicating Kendrick Lamar, since I'm not even that familiar with his work, but he did say he identifies as an Israelite and his cousin in that same song used some similar language to what is found in what Desean Jackson shared.
" you only have I known of all the families of the Earth, therefore I will punish you for all your iniquities." So until we come back to these commandments, until you come back to these commandments, we're gonna feel this way, we're gonna be under this curse. Because he said he's gonna punish us, the so-called Blacks, Hispanics, and Native American Indians, are the true children of Israel. We are the Israelites according to the Bible. The children of Israel, he's gonna punish us for our iniquities, for our disobedience, because we chose to follow other gods that aren't his son, so the Lord, thy God, chasten thee. So, just like you chasten your own son, he's gonna chastise you because he loves you. So that's why we get chastised, that's why we're in the position we're in. Until we come back to these laws, statutes and commandments, and do what the Lord said, these curses are gonna be upon us. We're gonna be at a lower state in this life that we live here in today, in the United States of America. I love you, son, and I pray for you. God bless you, Shalom."
It should also be said that at least one of the recent hate crimes against Jewish people were perpetrated by Black Israelites.
