'First' in the Bible

Therefore, I urge first of all [that] petitions, prayers, requests, [and] thanksgiving be made on behalf of all people,

For Adam was formed first, then Eve,

and these also must be tested first; then let them serve [if they] are above reproach.

But if any widow has children or grandchildren, they must learn to show profound respect for their own household first, and to pay back recompense to their parents, for this is pleasing in the sight of God.
