you sittest speakest against your brother; you slanderest your own mother's son.

Context
18 When you sawest a thief, then you consentedst with him, and hast been partaker with adulterers.
19 you givest your mouth to evil, and your tongue frameth deceit.
20 you sittest speakest against your brother; you slanderest your own mother's son.
21 These hast you done, and I kept silence; you thoughtest that I was altogether as thyself: I will reprove you, and set in order before your eyes.
22 Now consider this, ye that forget Elohim, lest I tear in pieces, and none to deliver.
