Numbers 15:9

[15:4]  ¹ tn The three words at the beginning of this verse are all etymologically related: “the one who offers his offering shall offer.”

[15:4]  ² sn Obviously, as the wording of the text affirms, this kind of offering would be made after they were in the land and able to produce the grain and oil for the sacrifices. The instructions anticipated their ability to do this, and this would give hope to them. The amounts are difficult to determine, but it may be that they were to bring 4.5 liters of flour and 1.8 liters each of oil and wine.

[15:9]  ³ tn The text changes from direct address here to the third person form of the verb. If the MT is correct, then to make a smooth translation it would need to be made a passive (in view of the fact that no subject is expressed).
