“Judah is gone into captivity because of affliction, and because of great servitude: she dwelleth among the heathen, she findeth no rest: all her persecutors overtook her between the straits.”
King James Version (KJV)
1:3 Because - Because of the servitude and oppression exercised among them: oppression by their rulers, and servitude more generally; keeping their servants beyond the year of jubilee, when they ought to be set at liberty. The straits - Those that pursued them overtook them in places where they could not escape.
