Commentary for I Samuel 22:22

וַיֹּ֨אמֶר דָּוִ֜ד לְאֶבְיָתָ֗ר יָדַ֜עְתִּי בַּיּ֤וֹם הַהוּא֙ כִּֽי־שָׁם֙ דויג [דּוֹאֵ֣ג] הָאֲדֹמִ֔י כִּֽי־הַגֵּ֥ד יַגִּ֖יד לְשָׁא֑וּל אָנֹכִ֣י סַבֹּ֔תִי בְּכָל־נֶ֖פֶשׁ בֵּ֥ית אָבִֽיךָ׃

And David said unto Abiathar: ‘I knew on that day, when Doeg the Edomite was there, that he would surely tell Saul; I have brought about the death of all the persons of thy father’s house.
