Anointing oil. Olive oil was mixed with spices and used to anoint priests, kings, prophets, and objects that were dedicated to God (Exodus 30:23–25; 1 Samuel 16:1). Anointing was a sign of God’s blessing, favor, and authority.
Grain offerings. Olive oil was added to flour and baked into cakes or wafers that were offered to God as a sacrifice of thanksgiving or devotion (Leviticus 2:1–10).
Cooking. Olive oil was used in preparing various foods, such as bread, cakes, and salads (Ezekiel 16:13).
Medicine. Olive oil was applied to wounds, bruises, and skin diseases as a healing agent (Isaiah 1:6; Luke 10:34).
Perfume. Olive oil was scented with fragrant herbs and used as a cosmetic or a gift (Song of Solomon 1:3; Luke 7:46).
Symbolism. Olive oil was a symbol of richness, joy, health, and the Holy Spirit (Jeremiah 31:12; Hebrews 1:9; Psalm 23:5; Matthew 25:1–13). It was also associated with peace, since the olive branch was a sign of the end of the flood in Noah’s time (Genesis 8:11).
