Some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction. 2 Peter 3:16
And it came to pass the third day, which was Pharaoh's birthday, that he made a feast unto all his servants: and he lifted up the head of the chief butler and of the chief baker among his servants. - Genesis 40:20
But when Herod's birthday was kept, the daughter of Herodias danced before them, and pleased Herod. - Matthew 14:6 (See also Mark 6:21)
The Pharaoh and KIng Herod had birthday parties, therefore you shouldn't.
(If you do you'll be destroyed at Armageddon.)
