(12) And now, O Israel, what does YHVH your God demand of you? Only this: to revere YHVH your God, to walk only in God's paths, to love God, and to serve YHVH your God with all your heart and soul, (13) keeping YHVH's commandments and laws, which I enjoin upon you today, for your good. (14) Mark, the heavens to their uttermost reaches belong to YHVH your God, the earth and all that is on it! (15) Yet it was to your ancestors that YHVH was drawn in love for them, so that God chose you, their lineal descendants, from among all peoples—as is now the case. (16) Cut away, therefore, the thickening about your hearts and stiffen your necks no more. (17) For YHVH your God is God supreme, the great, the mighty, and the awesome God, who shows no favor and takes no bribe, (18) but upholds the cause of the fatherless and the widow, and befriends the stranger, providing him with food and clothing.— (19) You too must befriend the stranger, for you were strangers in the land of Egypt.
(1) ערלת לבבכם [YOU SHALL CIRCUMCISE] THE FORESKIN OF YOUR HEART — This means: ye shall remove the closure and cover that is on your hearts, [which prevent My words gaining entrance to them] (cf. Rashi on Exodus 6:12 and Leviticus 19:23).
(12) But Moses appealed to YHVH saying, “The Israelites would not listen to me; how then should Pharaoh heed me, a man of impeded speech!”
(10) To whom shall I speak, Give warning that they may hear? Their ears are blocked And they cannot listen. See, the word of YHVH has become for them An object of scorn; they will have none of it.
