2 Samuel 21:8-10

Young's Literal Translation

⁸ and the king taketh the two sons of Rizpah daughter of Aiah, whom she bore to Saul, Armoni and Mephibosheth, and the five sons of Michal daughter of Saul whom she bare to Adriel son of Barzillai the Meholathite,

⁹ and giveth them into the hand of the Gibeonites, and they hang them in the hill before Jehovah; and the seven fall together, and they have been put to death in the days of harvest, in the first [days], the commencement of barley-harvest.

¹⁰ And Rizpah daughter of Aiah taketh the sackcloth, and stretcheth it out for herself on the rock, from the commencement of harvest till water hath been poured out upon them from the heavens, and hath not suffered a fowl of the heavens to rest upon them by day, or the beast of the field by night.
