וישלח - ביטחון והשתדלות
רבי ינאי בדיק ועבר רבי ינאי לטעמיה דאמר לעולם אל יעמוד אדם במקום סכנה לומר שעושין לו נס שמא אין עושין לו נס ואם עושין לו נס מנכין לו מזכיותיו אמר רבי חנין מאי קראה קטנתי מכל החסדים ומכל האמת רבי זירא ביומא דשותא לא נפיק לביני דיקלא
Rabbi Yannai would examine the ferry and cross. The Gemara comments that Rabbi Yannai acted in accordance with his reasoning stated elsewhere, as he said: A person should never stand in a place of danger saying that they on High will perform a miracle for him, lest in the end they do not perform a miracle for him. And, moreover, even if they do perform a miracle for him, they will deduct it from his merits. Rabbi Ḥanin said: What is the verse that alludes to this? When Jacob said: “I am not worthy of all the mercies, and of all the truth, which You have shown unto Your servant” (Genesis 32:11), and he explains: Since You have bestowed upon me so much kindness and truth, my merits have been diminished. Similarly, the Gemara relates that Rabbi Zeira would not go out and walk among the palm trees on a day when there was a southern wind blowing due to the fear that the trees might fall on him.

(יא) קָטֹ֜נְתִּי מִכֹּ֤ל הַחֲסָדִים֙ וּמִכָּל־הָ֣אֱמֶ֔ת אֲשֶׁ֥ר עָשִׂ֖יתָ אֶת־עַבְדֶּ֑ךָ כִּ֣י בְמַקְלִ֗י עָבַ֙רְתִּי֙ אֶת־הַיַּרְדֵּ֣ן הַזֶּ֔ה וְעַתָּ֥ה הָיִ֖יתִי לִשְׁנֵ֥י מַחֲנֽוֹת׃

(11) I am unworthy of all the kindness that You have so steadfastly shown Your servant: with my staff alone I crossed this Jordan, and now I have become two camps.

ונפש השנית בישראל היא חלק אלוק ממעל ממש, כמו שכתוב: "ויפח באפיו נשמת חיים" (בראשית ב, ז), ו"אתה נפחתה בי" (ברכת אלקי נשמה), וכמו שכתוב בזוהר‏: "מאן דנפח מתוכיה נפח", פירוש, מתוכיותו ומפנימיותו, שתוכיות ופנימיות החיות שבאדם מוציא בנפיחתו בכח.

The second soul in Israel is truly "a part of God above," as it is written: "and he blew into his nostrils a soul of life"(Genesis 2:7); "And You blew it into me." (Siddur, Morning Prayer). It is written in the Zohar "he Who blows, blows from within him," that is to say, from his inwardness and from his innermost being. For it is is of his inward and innermost vitality that a man emits through blowing with force.
