אַחֲרֵ֧י יְהוָ֛ה יֵלְכ֖וּ כְּאַרְיֵ֣ה יִשְׁאָ֑ג כִּֽי־ה֣וּא יִשְׁאַ֔ג וְיֶחֶרְד֥וּ בָנִ֖ים מִיָּֽם׃
They shall walk after the LORD, Who shall roar like a lion; For He shall roar, And the children shall come trembling from the west.
Rashi on Hosea
He shall roar like a lion He will yet roar to them like a lion that they leave the exile and follow Him.
Rashi on Hosea
and the children shall hasten from the west And the exiles shall be gathered from the west. [from Jonathan]
