'Log' in the Bible

“Now on the eighth day he is to take two male lambs without defect, and a yearling ewe lamb without defect, and three-tenths of an ephah of fine flour mixed with oil for a grain offering, and one log of oil;

Then the priest shall take the one male lamb and bring it for a guilt offering, with the log of oil, and present them as a wave offering before the Lord.

The priest shall also take some of the log of oil, and pour it into his left palm;

“But if he is poor and his means are insufficient, then he is to take one male lamb for a guilt offering as a wave offering to make atonement for him, and one-tenth of an ephah of fine flour mixed with oil for a grain offering, and a log of oil,

The priest shall take the lamb of the guilt offering and the log of oil, and the priest shall offer them for a wave offering before the Lord.
