4. sport yourselves—make a mock (Isa 66:5). Are ye aware of the glory of Him whom you mock, by mocking His servants ("the righteous," Isa 57:1)? (2Ch 36:16).
make … wide mouth—(Ps 22:7, 13; 35:21; La 2:16).
children of transgression, &c.—not merely children of transgressors, and a seed of false parents, but of transgression and falsehood itself, utterly unfaithful to God.
