When thou sawest a thief, then thou consentedst with him, and hast been partaker with adulterers.
Ver. 18. When thou sawest a thief, then thou consentedst with him] Mala opera hic memorata sunt in secreto, saith Kimchi. These evils hereafter mentioned are secretly acted by those that pretended to better things, see Eph 5:12 and, therefore, heaven and earth are called to witness against them, Psalms 50:4. See Jeremiah 20:2,7 Servi ut taceant iumenta loquentur, the very beasts have a verdict to pass upon secret sinners, as the ass upon Balaam, and those horses upon Cardinal Angelot, who was so basely covetous that by a secret way he used to go into his own stable, and steal the oats from them (Pontan. lib. de Prin.).
And hast been partaker with the adulterers] 1. In thy desire, supposing thyself with them. 2. In thy filthy acts, though closely carried; as the Popish priests, whose rule is, Si non caste, lumen caute.
