Commentary for II Samuel 4:10

כִּ֣י הַמַּגִּיד֩ לִ֨י לֵאמֹ֜ר הִנֵּה־מֵ֣ת שָׁא֗וּל וְהֽוּא־הָיָ֤ה כִמְבַשֵּׂר֙ בְּעֵינָ֔יו וָאֹחֲזָ֣ה ב֔וֹ וָאֶהְרְגֵ֖הוּ בְּצִֽקְלָ֑ג אֲשֶׁ֥ר לְתִתִּי־ל֖וֹ בְּשֹׂרָֽה׃

when one told me, saying: Behold, Saul is dead, and he was in his own eyes as though he brought good tidings, I took hold of him, and slew him in Ziklag, instead of giving a reward for his tidings.
