Numbers 7:2-3 ▼

2 Then the leaders of Israel, the heads of their fathers’ households, brought an offering near (they were the leaders of the tribes; they were the ones who were over the numbered men).

3 And they brought their offering before Yahweh, six covered carts and twelve oxen, a cart for every two of the leaders and an ox for each one, and they brought them near before the tabernacle.
