Literally, “To what purpose is this to Me, that incense cometh to Me?”
incense ... cane - (Isa 43:24; Isa 60:6). No external services are accepted by God without obedience of the heart and life (Jer 7:21; Psa 50:7-9; Isa 1:11; Mic 6:6, etc.).
sweet ... sweet - antithesis. Your sweet cane is not sweet to Me. The calamus.
