'Descendants Of Levi' in the Bible

Then the priests, the descendants of Levi, shall come near, for Yahweh your God has chosen them to bless in the name of Yahweh, and every legal dispute and every [case of] assault will be {subject to their ruling}.

So Moses wrote this law, and he gave it to the priests, the descendants of Levi, the [ones] carrying the ark of the covenant of Yahweh, and to all the elders of Israel.
