You do err,not knowing the scripture nor the commandments of God.
Romans 11:26-27 ...and 149 more
... and if you doubt what Paul said
1Cor.14:37
Neither of your Scripture citations are actually relevant to Angelino’s question as to when the United States established a “covenant” with Israel. (Which would be never. We have treaties and diplomatic agreements, but no covenants.)
Then again, it would also be incumbent on you to prove that those verses also apply to the modern state of Israel (a manmade creation that prides itself on being the most LGBT-friendly nation in the Middle East) simply because it shares the same name with the Biblical kingdom/people that God actually DID establish a covenant with.
