Joshua 4:12

Hence God turned the people to the way of the wilderness to the Red Sea; and the sons of Israel went up in battle array from the land of Egypt.

Of the sons of Gad, their genealogical registration by their families, by their fathers’ households, according to the number of names, from twenty years old and upward, whoever was able to go out to war,

but we ourselves will be armed ready to go before the sons of Israel, until we have brought them to their place, and our little ones live in the fortified cities because of the inhabitants of the land.

but your servants, everyone who is armed for war, will cross over in the presence of Yahweh to battle, just as my lord says.”

“Then I commanded you at that time, saying, ‘Yahweh your God has given you this land to possess it; all you men of valor shall cross over armed before your brothers, the sons of Israel.

“Then he provided the first part for himself, For there the ruler’s portion was reserved; And he came with the heads of the people; He did the righteousness of Yahweh, And His judgments with Israel.”
