וַיַּגֶּד־ל֤וֹ שְׁמוּאֵל֙ אֶת־כָּל־הַדְּבָרִ֔ים וְלֹ֥א כִחֵ֖ד מִמֶּ֑נּוּ וַיֹּאמַ֕ר יְהוָ֣ה ה֔וּא הַטּ֥וֹב בְּעֵינָ֖ו יַעֲשֶֽׂה׃ (פ)
And Samuel told him all the words, and hid nothing from him. And he said: ‘It is the LORD; let Him do what seemeth Him good.’
Or HaChaim
א־דני אלוקים אתה החילות להראות, "O Lord G'd, You have begun to show, etc." This (א־ד־נ־י) form of address may be understood as similar to Samuel I 3,18 where the High Priest Eli after being told by his pupil Samuel that G'd said that He would exact retribution from the house of Eli, reacted by saying: "My Master (א־ד־נ־י) will do whatever seems good in His eyes." Eli meant that when a master loses a servant such a loss is keenly felt by him; as a result, The Master would not agree to lose the servant unless He had good reason. When Moses used the word א־ד־נ־י in this instance he meant to say that his own success and wellbeing was a matter for his master (G'd) to evaluate.
