'First' in the Bible

First of all, then, I urge that entreaties and prayers, petitions and thanksgivings, be made on behalf of all men,

For it was Adam who was first created, and then Eve.

These men must also first be tested; then let them serve as deacons if they are beyond reproach.

but if any widow has children or grandchildren, they must first learn to practice piety in regard to their own family and to make some return to their parents; for this is acceptable in the sight of God.
