Lion in Wikipedia
Lion. - Now extinct in Israel and in the surrounding countries, the lion was common there during the Old Testament times; hence the great number of words in the Hebrew language to signify it; under one or another of these names it is mentioned 130 times in the Scriptures, as the classical symbol of strength, power, courage, dignity, ferocity. Very likely as the type of power, it became the ensign of the tribe of Juda; so was it employed by Solomon in the decoration of the temple and of the king's house. For the same reason, Apoc., v, 5, represents Jesus Christ as the lion of the tribe of Juda. The craft and ferocity of the lion, on the other hand, caused it to be taken as an emblem of Satan (1 Peter 5:8) and of the enemies of the truth (2 Timothy 4:17).
