'Custom' in the Bible

And Manoah saith, 'Now let thy words come to pass; what is the custom of the youth -- and his work?'

And the five men go, and come in to Laish, and see the people which is in its midst, dwelling confidently, according to the custom of Zidonians, quiet and confident; and there is none putting to shame in the land in any thing, possessing restraint, and they are far off from the Zidonians, and have no word with any man.
