G4914–συνήθεια–sunētheia

But every year you make a request to me to let a prisoner go free at the Passover. Is it your desire that I let the King of the Jews go free?

συνήθεια sunētheia “a custom”

Still, all men have not that knowledge: but some, being used till now to the image, are conscious that they are taking food which has been offered to the image; and because they are not strong in the faith, their minds are troubled.

συνηθείᾳ sunētheia “by custom”

But if any man will not be ruled in this question, this is not our way of doing things, and it is not done in the churches of God.
