The other Gentiles are non Israelites represented by the other animals and the children of Israel are represented as being the Lions particularly from the Tribe of Judah!
Gen 49:9 Judah is a lion's whelp: from the prey, my son, thou art gone up: he stooped down, he couched as a lion, and as an old lion; who shall rouse him up?
Representing when the children of Israel had to flee into the wilderness and live among the gentiles!
Luk 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
The children of Israel living among the gentiles and dealing with things and eating food that our forefathers did not know!
