G4914–συνήθεια–sunētheia

But you have a custom that I should release one prisoner to you at the Passover. So shall I release to you the King of the Jews?"

συνήθεια sunētheia “a custom”

But all believers do not recognize these facts. Some, from force of habit in relation to the idol, even now eat idol sacrifices as such, and their consciences, being but weak, are polluted.

συνηθείᾳ sunētheia “by custom”

But if any one is inclined to be contentious on the point, we have no such custom, nor have the Churches of God.
