2 Samuel 9:12ESV·author unknown

And Mephibosheth had a young son, whose name was Mica. And all who lived in Ziba’s house became Mephibosheth’s servants.

Matthew Henry Presbyterian @wholebiblehenry

The matter is here settled concerning Mephibosheth. 1. This grant of his father's estate is confirmed to him, and Ziba called to be a witness to it (Sa2 9:9); and, it should seem, Saul had a very good estate, for his father was a mighty man of substance (Sa1 9:1), and he had fields and vineyards to bestow, Sa1 22:7.

And Mephibosheth had a young son, whose name was Micha,.... What his age was is not said from him sprung a progeny of several generations, Ch1 8:34, and all that dwelt in the house Ziba were servants to Mephibosheth; his sons and his servants.

Mephibosheth had a young son, whose name was Micah--Whether born before or after his residence in Jerusalem, cannot be ascertained. But through him the name and memory of the excellent Jonathan was preserved (see Ch1 8:34-35; Ch1 9:40-41). Next: 2 Samuel Chapter 10
