Translation
rather you must each remember that you were a slave in EGYPT and YHVH your ELOHIM (read Adonai your Elohim) redeemed you from there; based on this, I forcefully command you to do this thing.
Paraphrase
instead you must each remember that you were a slave in the place that is BOUND BY SIN and THE ETERNAL AND PERSONAL GOD who is YOUR CREATOR AND RULER freed you from that place; based on the debt of gratitude you owe me, I firmly charge you to treat the disadvantaged properly.
