Blot out. — The figure is most probably, as in Exodus 32:32-33, taken from the custom of erasing a written record (comp. Numbers 5:23; Psalms 69:28). So LXX. and Vulg. Isaiah, however (Isaiah 44:22) uses the same word in a different connection, “I will blot out thy sins as a cloud.” A fine thought that the error and guilt that cloud the mind and conscience can be cleared off like a mist by a breath from heaven.
Transgressions. — See Psalms 32:1. The word seems to imply a wilful throwing off of authority or restraint, perhaps here the breach of the covenant-relation irrespective of any particular sin by which the breach was brought about. Whether it is an individual or the community that speaks, the prayer is that Jehovah would act according to His chesed or covenant-favour towards the suppliant, and wipe out from His records whatever has intervened between the covenant parties.
