Isaiah 43:23-24

The people had brought few sacrifices and offerings to the Lord, even though His requirements of them in this regard were not excessive, and even what they had brought had not touched Him. Sweet cane (calamus) was an ingredient in the anointing oil (cf. Exodus 30:23; Jeremiah 6:20). What they had brought to Him in abundance was sin and iniquity. He was wearier of their worship than they were.
