C. F. Keil and Franz Delitzsch on Proverbs 28:15

Pro 28:15

This general ethical proverb is now followed by one concerning the king: 15 A roaring lion and a ravening bear      Is a foolish ruler over a poor people,i.e., a people without riches and possessions, without lasting sources of help - a people brought low by the events of war and by calamities. To such a people a tyrant is a twofold terror, like a ravenous monster. The lxx translate מושׁל רשׁע by ὃς τυραννεῖ πτωχὸς ὤν, as if רשׁ had been transferred to this place from Pro 28:3. But their translation of רשׁע, Pro 29:7, wavers between ἀσεβής and πτωχός, and of the bear they make a wolf זאב, dialectical דּיב. שׁוקק designates a bear as lingering about, running hither and thither, impelled by extreme hunger (Venet. ἐπιοῦσα), from שׁקק = שׁוּק, to drive, which is said of nimble running, as well as of urging impulses (cf. under Gen 3:16), viz., hunger.
