Exodus 30:35 (b) This sweet fragrance represents the beautiful character of the Lord JESUS which is fragrant to GOD, and very precious, sweet and fragrant to us. By His sacrifice on the altar. He offered up to GOD the worship and adoration of His own heart for His Father, and to His GOD. This is pictured in the incense burning in the Holy place. It could not be used by anyone for personal use ( Exodus 30:37).
Proverbs 7:17 (c) It is always true that Satan makes lustful pleasures very attractive and appealing to the senses. This is true also in Isaiah 57:9.
Song of Solomon 3:6 (c) This no doubt refers to the loveliness of the Lord JESUS CHRIST who is admired by His people, and whose Name is as ointment poured forth.
