'Lamb...' im assuming is a metaphor
-------------
Cmte, Yes a metaphor,and one that could be readily understood.
Throughout the Bible, sheep played a notable role in the remission of sin and approach to God. For instance, after Abraham had demonstrated that he was willing to offer his son Isaac, he was told not to harm Isaac and was provided with a ram, or male sheep, as a substitute. (Gen. 22:12, 13) When the Israelites were delivered from Egypt, sheep again played a significant role, this time as part of “Jehovah’s passover.” (Ex. 12:1-13) Further, the Mosaic Law provided for the sacrifice of various animals, including sheep and goats.—Ex. 29:38-42; Lev. 5:6, 7.
So when Jesus was introduced as "the Lamb of God that takes away the sin of the world" it was to foretell the role he would play in the forgiveness of sin that could be appreciated after his sacrificial death. Thus it was not to no purpose that animals were sacrificed.
