'Add' in the Bible
Yahweh, the God of your ancestors, may he add to you as you are [now] a thousand times, and may he bless you just as he {promised you}.
You must not add to the word that I [am] commanding you, and you shall not take away from it [in order] to keep the commands of Yahweh your God that I [am] commanding you [to observe].
"These words Yahweh spoke to your whole assembly at the mountain from the midst of the fire and the very thick cloud [with] a loud voice, and {he did not add anything}, and [then] he wrote them on two tablets of stone and gave them to me.
All of the things that I [am] commanding you, {you must diligently observe}; you shall not add to it, and you shall not take away from it."
[then] {if you diligently observe this entire commandment} that I [am] commanding you {today} by loving Yahweh your God and by going in his ways {at all times}, then you shall add three more cities for yourselves to these three.
