for the Bread of the Presence also and for the fine flour for a grain offering, whether of unleavened wafers or of what is baked in the pan or of what is soaked, and for all measurements of quantity and size; Bible

“and for all measurements of quantity and size.” David knew how important it was in a kingdom to have accurate weights and measures to insure fair trade, and he officially put the Levites in charge of standardizing weights and measures. They were likely unofficially in charge of that earlier, but that is not clear. Early in history, weights and measures often varied from town to town. See commentary on Leviticus 19:35.
