Thy silver is become dross, thy wine mixed with water:
Thy silver is become dross, thy wine mixed with water - Thy princes and people are degenerate in solid worth ("silver," Jeremiah 6:28; Jeremiah 6:30; Ezekiel 22:18-19), and in their use of the living Word ('the undiluted wine,' Song of Solomon 7:9).
Mixed - mahul; literally, circumcised (Talmud). So the Arabic to murder wine, for to dilute it. Like Moses, Deuteronomy 10:16, "Circumcise the foreskin of your hearts," Isaiah glances at their tendency to rely on the outward circumcision, without the inward spirit, the true wine of the ordinance.
