At that time Joshua imposed this curse:

The man who undertakes
the rebuilding of this city, Jericho,
is cursed before the Lord.
He will lay its foundation
at the cost of his firstborn;
he will set up its gates
at the cost of his youngest.

This was the allotment for the tribe of Manasseh as Joseph’s firstborn. Gilead and Bashan came to Machir, the firstborn of Manasseh and the father of Gilead, who was a man of war.
