And grieve not the holy Spirit of God; viz. by corrupt communication. The Spirit is said to be grieved when any thing is done by us, which, were he capable of such passions, might be matter of grief to him; or when we so offend him as to make him withdraw his comfortable presence from us: see Isa_63:10.
Whereby ye are sealed; set apart or marked for, and secured unto the day of redemption; see Eph_1:142Co_1:22: so, Eze_9:4, they are marked that are to be delivered; and Rev_7:3, the servants of God are sealed that were to escape the following plagues.
Unto the day of redemption; i.e. full and final salvation at the resurrection: see Luk_21:28Rom_8:23.
