Definition: The word "ecac" doesn't appear in the Bible, but I can provide a short definition: ECAC: Eccl. 29:1-6 (ESV) "The children of Israel were living well and prospering; then God brought upon them famine, so that they could not satisfy themselves with the good things of this world. The word "ecac" translates to "famine." In this verse, God brings on a famine so that the Israelites can't continue to feed their people without suffering.
