3 Bible Verses about Vowing To Fast

And when it was day, some of the Jews entering into a conspiracy, bound themselves under a curse, saying, That they would neither eat nor drink, till they had killed Paul.

And they came to the chief priests and elders, and said, We have bound ourselves by a solemn curse, not to taste anything, till we have killed Paul.

But do not yield to them; for there are more than forty of them lie in wait, who have bound themselves with a curse, neither to eat nor drink till they have killed him: and now are they ready, expecting a promise from thee.
