Adam Clarke on Numbers 15:5

The fourth part of a hin - The quantity of meal and flour was augmented in proportion to the size of the sacrifice with which it was offered. With a Lamb or a Kid were offered one tenth deal of flour, (the tenth part of an ephah, see on Exo 29:40 (note)), the fourth part of a hin of oil, and the fourth part of a hin of wine. With a Ram, two tenth deals of flour, a third part of a hin of oil, and a third part of a hin of wine. With a Bullock, three tenth deals of flour, half a hin of oil, and half a hin of wine. See Num 15:4-11.
