And know ye this day: for I speak not with your children which have not known, and which have not seen the chastisement of the LORD your God, his greatness, his mighty hand, and his stretched out arm,
And consider today (since I am not speaking to your children who have not known or seen it), consider the discipline of the LORD your God, his greatness, his mighty hand and his outstretched arm,
Keep in mind that I am not talking now to your children, who have never experienced the discipline of the LORD your God or seen his greatness and his strong hand and powerful arm.
