Numbers 29:13  (King James Version)
And ye shall offer a burnt offering, a sacrifice made by fire, of a sweet savour unto the LORD; thirteen young bullocks, two rams, and fourteen lambs of the first year; they shall be without blemish:

thirteen young bullocks
Numbers 29:2 Numbers 29:8 ; Numbers 28:11 Numbers 28:19 Numbers 28:27 Ezra 3:4 ; Hebrews 10:12-14
At this feast thirteen bullocks, two rams, and fourteen lambs, were to be offered. It is worthy of remark, that in each of the seven days of this feast one bullock is to be abated, so that on the seventh day (ver. 32) they were to offer seven bullocks, but the rams and lambs were every day alike; which appointment might signify a diminishing and wearing away of the legal offerings, to lead them to the spiritual and reasonable service, by presenting their own bodies a living sacrifice, holy, and acceptable unto God.
Romans 12:1
