What the Bible says about Misuse of Feast
(From Forerunner Commentary)
These verses give a vivid picture of the wrong kind of "rejoicing." In this context, "feast" does not necessarily imply a holy day. However, it shows that we can have the good things of life as a blessing from God, yet misuse them by removing God and His purpose from their proper enjoyment.
