1 Samuel 17:30

וַיִּשְׁמַע אֱלִיאָב אָחִיו הַגָּדוֹל בְּדַבְּרוֹ אֶל־הָאֲנָשִׁים וַיִּֽחַר־אַף אֱלִיאָב בְּדָוִד וַיֹּאמֶר לָמָּה־זֶּה יָרַדְתָּ וְעַל־מִי נָטַשְׁתָּ מְעַט הַצֹּאן הָהֵנָּה בַּמִּדְבָּר אֲנִי יָדַעְתִּי אֶת־זְדֹנְךָ וְאֵת רֹעַ לְבָבֶךָ כִּי לְמַעַן רְאוֹת הַמִּלְחָמָה יָרָֽדְתָּ

And Eliab his eldest brother heard when he spoke unto the men; and Eliab’s anger was kindled against David, and he said: ‘Why art thou come down? and with whom hast thou left those few sheep in the wilderness? I know thy presumptuousness, and the naughtiness of thy heart; for thou art come down that thou mightest see the battle.’

וַיֹּאמֶר דָּוִד מֶה עָשִׂיתִי עָתָּה הֲלוֹא דָּבָר הֽוּא

And David said: ‘What have I now done? Was it not but a word?’

וַיְּשָּֽׁמְעוּ הַדְּבָרִים אֲשֶׁר דִּבֶּר דָּוִד וַיַּגִּדוּ לִפְנֵֽי־שָׁאוּל וַיִּקָּחֵֽהוּ

And when the words were heard which David spoke, they rehearsed them before Saul; and he was taken to him.

וַיֹּאמֶר דָּוִד אֶל־שָׁאוּל אַל־יִפֹּל לֵב־אָדָם עָלָיו עַבְדְּךָ יֵלֵךְ וְנִלְחַם עִם־הַפְּלִשְׁתִּי הַזֶּֽה

And David said to Saul: ‘Let no man’s heart fail within him; thy servant will go and fight with this Philistine.’
