וַיֹּאמֶר֮ דָּוִד֒ יְהוָ֗ה אֲשֶׁ֨ר הִצִּלַ֜נִי מִיַּ֤ד הָֽאֲרִי֙ וּמִיַּ֣ד הַדֹּ֔ב ה֣וּא יַצִּילֵ֔נִי מִיַּ֥ד הַפְּלִשְׁתִּ֖י הַזֶּ֑ה (ס) וַיֹּ֨אמֶר שָׁא֤וּל אֶל־דָּוִד֙ לֵ֔ךְ וַֽיהוָ֖ה יִהְיֶ֥ה עִמָּֽךְ׃
At sinabi ni David: “Ang Walang-Hanggan na nagligtas sa akin mula sa kamay ng leon at mula sa kamay ng oso ay siya ring magliligtas sa akin mula sa kamay ng Filisteong ito.” At sinabi ni Saul kay David: “Humayo ka, at ang Walang-Hanggan ay sasaiyo.”

Adonoy Who saved me from the claws of the lion. I know that this incident did not occur to me for naught, but as an indication that in the future, I would be confronted with similar circumstances, as a salvation for Yisroel. I will therefore rely on this, and go out. And he was one of two righteous men, to whom [God] gave a hint, and they understood the matter, Dovid and Mordechai, as it is stated: "And every day Mordechai would walk before the courtyard…"18Megillas Esther 2:11. He said [to himself], 'It is not for naught that this righteous woman [Esther] has been taken into the bed of this uncircumcised one [Achashveirosh]. It can only mean that she is destined to stand up on behalf of Yisroel at a time of distress.'
