'Customary' in the Bible

On the first day [of the festival] of Unleavened Bread, when [as was customary] they sacrificed the Passover lamb, His disciples asked Him, “Where do You want us to go and prepare for You to eat the Passover?”

Prompted by the Spirit, he came into the temple [enclosure]; and when the parents brought in the child Jesus, to do for Him the custom required by the Law,

So they took Jesus’ body and bound it in linen wrappings with the fragrant spices, as is the burial custom of the Jews.
