Da Lamb

When one opens the Old Testament and start reading, the first mention of the word lamb is in reference to a 'burnt offering'. The second mention (in the same dialog) is a prophetic statement about the Lord Jesus Christ:

And Isaac spake unto Abraham his father, and said, My father: and he said, Here [am] I, my son. And he said, Behold the fire and the wood: but where [is] the lamb for a burnt offering? And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together. Gen. 22:7-8 KJV

When one opens the door of the tabernacle and enters, the first time one would see a lamb is by the time he got to the altar of burnt offering, the first piece of furniture.

And this is what thou shalt offer upon the altar -- two lambs of the first year, day by day continually. The one lamb thou shalt offer in the morning; and the other lamb thou shalt offer between the two evenings. And with the one lamb a tenth part of wheaten flour mingled with beaten oil, a fourth part of a hin; and a drink-offering, a fourth part of a hin of wine. nd the second lamb shalt thou offer between the two evenings; as the oblation in the morning, and as its drink-offering shalt thou offer with this, for a sweet odour, an offering by fire to Jehovah. It shall be a continual burnt-offering throughout your generations at the entrance of the tent of meeting before Jehovah, where I will meet with you, to speak there with thee. Exodus 29:38-42

Lamb was also use for the trespass offering, the sin offering and the peace offering. In each of these offerings, the lamb provided atonement for sins.

When one opens the New Testament and start reading, the first mention of the word lamb is the fulfilment of the prophecy in Genesis 22 as well as the anti-type of each and every lamb that was ever offered as a burnt, peace, sin, or trespass offering:

On the morrow he sees Jesus coming to him, and says, Behold the Lamb of God, who takes away the sin of the world. John 1:36

The lamb in the offerings covered sin, with the sacrifice of Jesus, sins are actually taken away.

And every priest stands daily ministering, and offering often the same sacrifices, which can never take away sins. But he, having offered one sacrifice for sins, sat down in perpetuity at [the] right hand of God, waiting from henceforth until his enemies be set [for the] footstool of his feet. For by one offering he has perfected in perpetuity the sanctified. Heb. 10:11-14
