A lamb (almost a lion)

The lamb is mentioned many times in Tanak (Old Testament), mostly in reference to its role in the peace offering, sin offering and the Passover festival.

“If the offering is a burnt offering from the flock, from either the sheep or the goats, you are to offer a male without defect.”
‭‭Leviticus‬ ‭1:10‬ ‭NIV‬‬

By the time of the B’rit hadashah (New Testament) the lamb takes on very strong symbolic meaning, even as a name.

“They will make war against the Lamb, and the Lamb will overcome them—because He is Lord of lords and King of kings, and those with Him are called and chosen and faithful.”
‭‭The Revelation‬ ‭17:14‬ ‭TLV‬‬
