'Usual' in the Bible

Then on the seventh day they got up early at daybreak and marched around the city in the same way seven times; only on that day they marched around the city seven times.

And behold, there was a wall all around the outside [area] of the temple (house) [of the Lord], and in the man’s hand a measuring rod six cubits long (10.2 ft.), each cubit being longer than the standard one by a hand width. So he measured the thickness of the wall, one rod; and the height, one rod.

Then Paul took the [four] men, and the next day he purified himself along with them [by submitting to the ritual]. He went into the temple to give notice of [the time] when the days of purification [ending each vow] would be fulfilled and the usual offering could be presented on behalf of each one.

Then he prayed again, and the sky gave rain and the land produced its crops [as usual].
