1 Sam 20:3

וַיִּשָּׁבַ֨ע ע֜וֹד דָּוִ֗ד וַיֹּ֨אמֶר֙ יָדֹ֨עַ יָדַ֜ע אָבִ֗יךָ כִּֽי־מָצָ֤אתִי חֵן֙ בְּעֵינֶ֔יךָ וַיֹּ֛אמֶר אַל־יֵֽדַע־זֹ֥את יְהוֹנָתָ֖ן פֶּן־יֵֽעָצֵ֑ב וְאוּלָ֗ם חַי־יְהוָה֙ וְחֵ֣י נַפְשֶׁ֔ךָ כִּ֣י כְפֶ֔שַׂע בֵּינִ֖י וּבֵ֥ין הַמָּֽוֶת׃

But David again vowed, “Your father knows very well that I have found favor in your eyes, and he has said, ‘Jonathan must not know of this, or he will be grieved.’ As surely as the LORD lives and as you yourself live, there is but a step between me and death.”
