'Joy' in the Bible

Then he said unto them, Go your way, eat the fat, and drink the sweet, and send portions unto him for whom nothing is prepared; for this day is holy unto our Lord: neither be ye grieved; for the joy of Jehovah is your strength.

And they offered great sacrifices that day, and rejoiced; for God had made them rejoice with great joy; and the women also and the children rejoiced: so that the joy of Jerusalem was heard even afar off.
