Psalm 104:15 NKJV
And wine that makes glad the heart of man, Oil to make his face shine, And bread which strengthens man's heart.
The psalmist praised God for wonderful things the Lord had done. He mentioned how God provided oil for humanity to make the face shine.
Spiritual parallel: Just as natural oil will cause a natural shine to be visible on the skin, the oil of the Holy Spirit and the anointing will bring a spiritual shine - a glow upon us. In other words, we will stand out and be recognized as being associated with the Lord because of His goodness being manifested through us. Isaiah 60:1 NKJV says, "Arise, shine; For your light has come! And the glory of the LORD is risen upon you."
