Matthew 6:17

³Therefore wash yourself, anoint yourself, get dressed, and go down to the threshing floor; but don’t make yourself known to the man until he has finished eating and drinking.

⁸Let your garments be always white, and don’t let your head lack oil.

²In those days I, Daniel, was mourning three whole weeks. ³I ate no pleasant food. No meat or wine came into my mouth. I didn’t anoint myself at all, until three whole weeks were fulfilled.

²⁰Then David arose from the earth, and washed and anointed himself, and changed his clothing; and he came into the LORD’s house, and worshiped. Then he came to his own house; and when he requested, they set bread before him and he ate.

²Joab sent to Tekoa and brought a wise woman from there, and said to her, “Please act like a mourner, and put on mourning clothing, please, and don’t anoint yourself with oil; but be as a woman who has mourned a long time for the dead.
