peacemakers dr. bill, a more full quotation for you:

--9 Blessed are the peacemakers, / For they shall be called sons of God.
-10 Blessed are those who are persecuted for righteousness' sake, / For theirs is the kingdom of heaven.
-11 Blessed are you when they revile and persecute you, and say all kinds of evil against you falsely for My sake.

A nuance is that "to make" is an active verb; e.g., "those who work for peace"; "the makers and maintainers of peace"; "those who make peace" (New Living Translation; Amplified Bible: Worldwide English)
