Charles Ellicott Commentary Hosea 4:2

"There is nought but swearing and breaking faith, and killing, and stealing, and committing adultery; they break out, and blood toucheth blood." — Hosea 4:2 (ASV)

Blood toucheth blood — that is, murder is added to murder with ghastly prevalence. References to false swearing and lying are repeated in terrible terms by Amos 2:6-8 and Micah 7:2-8; and the form of the charge suggests the Decalogue and pre-existing legislation (Exodus 20:13–15).
