'Wild' in the Bible

For this reason I will mourn and wail; I will walk around barefoot and without my outer garments. I will howl like a wild dog, and screech like an owl.

And the remnant of Jacob will be among the nations, in the midst of many peoples, like a lion among the wild animals of the forest, like a young lion among the herds of sheep which, when it passes through and treads [down] and tears in pieces, there is none who [can] deliver.
