But ye shall offer a burnt offering, a sacrifice made by fire, of a sweet savour unto the Lord: one bullock, one ram, seven lambs of the first year without blemish:

but ye shall offer a burnt-offering, an offering made by fire, of a sweet savor unto Jehovah: one bullock, one ram, seven he-lambs a year old without blemish;

And give a burned offering, an offering made by fire of a sweet smell to the Lord: one ox, one male sheep, seven he-lambs of the first year, without any mark:

and ye have brought near a burnt-offering, a fire-offering, a sweet fragrance, to Jehovah; one bullock, one ram, seven lambs, sons of a year, perfect ones;

But you shall offer a holocaust for a most sweet odour to the Lord, one calf, one ram, and seven lambs of a year old, without blemish:

And ye shall present a burnt-offering, an offering by fire of a sweet odour to Jehovah: one bullock, one ram, seven yearling lambs without blemish;
