'Joy' in the Bible

then the man shall bring his wife to the priest, and he shall bring as an offering for her, a tenth of an ephah of barley meal; he shall not pour oil on it nor put frankincense on it [the symbols of favor and joy], because it is a grain offering of jealousy, a memorial grain offering, a reminder of [the consequences of] wickedness.

"And on the day of your joy and in your appointed times, at the beginning of your months, you will blow on the trumpets in addition to your burnt offerings and in addition to the sacrifices of your fellowship offerings. And they will be as a memorial for you {before} your God; I [am] Yahweh your God."
