1 Sam 17:39

וַיַּחְגֹּ֣ר דָּוִ֣ד אֶת־חַ֠רְבּוֹ מֵעַ֨ל לְמַדָּ֜יו וַיֹּ֣אֶל לָלֶכֶת֮ כִּ֣י לֹֽא־נִסָּה֒ וַיֹּ֨אמֶר דָּוִ֜ד אֶל־שָׁא֗וּל לֹ֥א אוּכַ֛ל לָלֶ֥כֶת בָּאֵ֖לֶּה כִּ֣י לֹ֣א נִסִּ֑יתִי וַיְסִרֵ֥ם דָּוִ֖ד מֵעָלָֽיו׃

David strapped his sword over the tunic and tried to walk, but he was not accustomed to them. “I cannot walk in these,” David said to Saul. “I am not accustomed to them.” So David took them off.
