If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the LORD. Burnt-sacrifice - The most important of all the sacrifices offered to God; called by the Septuagint ὁλοκαυτωμα, because it was wholly consumed, which was not the case in any other offering. See on Leviticus 7 (note).
His own voluntary will - לרצנו lirtsono, to gain himself acceptance before the Lord: in this way all the versions appear to have understood the original words, and the connection in which they stand obviously requires this meaning.
