2 Samuel 20:4

²And all the men of Israel went up from following David after Sheba the son of Bichri: but the men of Judah adhered to their king, from Jordan even to Jerusalem.

³And David went into his house at Jerusalem: and the king took the ten women his concubines, whom he had left to keep the house, and he put them in a place of custody, and maintained them, and went not in to them; and they were kept living as widows, till the day of their death.

— 2 Samuel 20:4 —

⁵And Amasa went to call Judah, and delayed beyond the time which David appointed him.

⁶And David said to Amasa, Now shall Sheba the son of Bichri do us more harm than Absalom: now then take thou with thee the servants of thy lord, and follow after him, lest he find for himself strong cities, so will he blind our eyes.
