bring forth for trouble - literally, “for terror,” that is, “They shall not bring forth children for a sudden death” (Lev 26:16; Jer 15:8).
seed ... blessed - (Isa 61:9).
offspring with them - (Hos 9:12). “Their offspring shall be with themselves” [Maurer]; not “brought forth” only to be cut off by “sudden death” (see the parallel clause).
