'Well fed' in the Bible

Woe to you who are well-fed now, for you shall be hungry. Woe to you who laugh now, for you shall mourn and weep.

I know how to get along and live humbly [in difficult times], and I also know how to enjoy abundance and live in prosperity. In any and every circumstance I have learned the secret [of facing life], whether well-fed or going hungry, whether having an abundance or being in need.
