Adam Clarke on 1 Samuel 25:1

And Samuel died - Samuel lived, as is supposed, about ninety-eight years; was in the government of Israel before Saul from sixteen to twenty years; and ceased to live, according to the Jews, about four months before the death of Saul; but according to Calmet and others, two years. But all this is very uncertain; how long he died before Saul, cannot be ascertained. For some account of his character, see the end of the chapter, 1Sam 25:44 (note).

Buried him in his house - Probably this means, not his dwelling-house, but the house or tomb he had made for his sepulture; and thus the Syriac and Arabic seem to have understood it.

David - went down to the wilderness of Paran - This was either on the confines of Judea, or in Arabia Petraea, between the mountains of Judah and Mount Sinai; it is evident from the history that it was not far from Carmel, on the south confines of Judah.
