The lion and bear are always cruel and greedy in their natures, and especially when they are hungry and want prey, in which case the lions roar, Psalms 104:21 Isaiah 31:4, and bears range about for it. So is a wicked ruler; instead of being a nursing father, and a faithful and tender shepherd, as he ought to be, he is a cruel and insatiable oppressor and devourer of them: Over the poor people; whom he particularly mentions, either to note his policy in oppressing them only who were unable to withstand him, or to revenge themselves of him; or to aggravate his sin in devouring them, whom the laws of God and common humanity bound him to relieve and protect; or to express the effect of his ill government, in making his people poor by his frauds and rapines.
