TSK · Isaiah 21:8

when I remember you on my bed, and think about you in the night watches.

Their roaring will be like a lioness. They will roar like young lions. Yes, they shall roar, and seize their prey and carry it off, and there will be no one to deliver.

I have set watchmen on your walls, Jerusalem; they shall never hold their peace day nor night: you who call on Yahweh, take no rest,

He has left his covert, as the lion; for their land is become an astonishment because of the fierceness of the oppressing [sword], and because of his fierce anger.

Behold, [the enemy] shall come up like a lion from the pride of the Jordan against the strong habitation: for I will suddenly make them run away from it; and whoever is chosen, him will I appoint over it: for who is like me? and who will appoint me a time? and who is the shepherd who can stand before me?

Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour.
