'Festival' in the Bible
Now the Festival of Unleavened Bread was drawing near, which is called the Passover.
Later on there was a Jewish festival (feast) for which Jesus went up to Jerusalem.
Go to the Feast yourselves. I am not [yet] going up to the Festival, because My time is not ripe. [My term is not yet completed; it is not time for Me to go.]
Some thought that, since Judas had the money box (the purse), Jesus was telling him, Buy what we need for the Festival, or that he should give something to the poor.
