Charles Ellicott Commentary Leviticus 14:15

"And the priest shall take of the log of oil, and pour it into the palm of his own left hand;" — Leviticus 14:15 (ASV)

Shall take some of the log of oil. —This he had to do with his right hand, which is actually expressed in the ancient Chaldee paraphrase.

And pour it into the palm of his own left hand. —Better, and he shall pour it into the palm of the priest’s left hand, that is, the priest who has until now performed the ceremony of cleansing the leper now takes some of the log of oil and puts it into the left hand of his fellow priest. This is not only distinctly declared in the canons that prevailed during the second Temple, but is expressed in the text, as is evident from the literal translation we have given of the clause in question.

The same priest, however, was allowed to pour it into the palm of his own hands. To express this view, which the translators of the Authorised Version adopted, they omitted the word priest, which is found in the original, and substituted his own, which is not in the original.
