C. F. Keil and Franz Delitzsch on Leviticus 1:3-9

Lev 1:3-9 Ceremonial connected with the offering of an ox as a burnt-offering. עלה (vid., Gen 8:20) is generally rendered by the lxx ὁλοκαύτωμα or ὁλοκαύτωσις, sometimes ὁλοκάρπωμα or ὁλοκάρπωσις, in the Vulgate holocaustum, because the animal was all consumed upon the altar. The ox was to be a male without blemish (ἄμωμος, integer; i.e., free from bodily faults, see Lev 22:19-25), and to be presented “at the door of the tabernacle,” - i.e., near to the altar of burnt-offering (Exo 40:6), where all the offerings were to be presented (Lev 17:8-9), - “for good pleasure for him (the offerer) before Jehovah,” i.e., that the sacrifice might secure to him the good pleasure of God (Exo 28:38).
