Boyd’s Bible Dictionary:
(seeing). Once found in Palestine (Judg. 14:5-6; 1 Sam. 17:34-36; 2 Sam. 23:20). Symbol of strength (Gen. 49:9).
Concise Bible Dictionary:
There are several Hebrew words translated “lion,” the principal of which is ari, from “to tear.” The lion is declared to be the “strongest among beasts and turneth not away for any” (Prov. 30:30). This shows that the lion may be taken as a symbol of “strength,” and as such the Lord is called the lion of the tribe of Judah, to which is attached the symbol of royalty, for Judah held the scepter (Gen. 49:9-10; Rev. 5:5). Satan also has a kingdom and is called a strong one (Matt. 12:26); and he is the “lion” seeking whom he may devour. He is compared to a “roaring lion,” because he is like that animal, which roars when it is sure of its prey (compare Amos 3:4). The Lord knows how to deliver His servants even out of the mouth of the lion.
