The correct answer to this open question is the following.

Here we are talking about a treaty made by Native American Indian tribes with white Europeans. In this case, the of Plymouth Plantation with the Wampanoag Nation, in the North American territory.

One of the agreements was "He should send to his neighbor's confederates to certify them of this, that they might not wrong them, but might be likewise comprised in the conditions of peace." This meant that the Native Americans should maintain peace conditions with other tribes and white people, and that issue should be certified by the members of the tribes so no conflict could arise.

The Wampanoag-Pilgrim treaty of April 1621 was signed by chief Massasoit, leader of the Wampanoag, to establish good relationships between white English colonists and Native American Indians that already lived in the region.
