(ט) ... נֹ֗חַ אִ֥ישׁ צַדִּ֛יק תָּמִ֥ים הָיָ֖ה בְּדֹֽרֹתָ֑יו אֶת־הָֽאֱלֹהִ֖ים הִֽתְהַלֶּךְ־נֹֽחַ׃
(9) ... Noah was in his generations a man righteous and wholehearted; Noah walked with God.
(א) ...וַיֵּרָ֨א יְהוָ֜ה אֶל־אַבְרָ֗ם וַיֹּ֤אמֶר אֵלָיו֙ אֲנִי־אֵ֣ל שַׁדַּ֔י הִתְהַלֵּ֥ךְ לְפָנַ֖י וֶהְיֵ֥ה תָמִֽים׃
(1) ...the LORD appeared to Abram, and said unto him: ‘I am God Almighty; walk before Me, and be thou wholehearted.
והיה תמים AND BE PERFECT — This, too, is a command following upon the previous command: be whole-hearted in all the trials I impose upon you. According to the Midrash (ib.), however, it means: walk before Me by observing the precept of circumcision and through this you will become perfect, for so long as you are uncircumcised I regard you as having a blemish. Another explanation of היה תמים BE THOU PERFECT — at present you lack the power of controlling morally five organs, viz., two eyes, two ears and the membrum. Therefore will I add a letter (i. e. the letter 'ה the numerical value of which is five) to your name (אברם which equals 243) so that the total of the letters of your name (אברהם) will become 248, corresponding to the number of limbs of your body (cf. Nedarim 32b).
(יג) תָּמִ֣ים תִּֽהְיֶ֔ה עִ֖ם יְהוָ֥ה אֱלֹהֶֽיךָ׃ (ס)
תמים ת' גדולה שאם תלך בתמימות כאילו קיימת מאל''ף ועד תי''ו:
Whole-hearted: The letter 'Tav' is large, indicating that if you go whole-heartedly, it is as if you have fulfilled from 'Aleph' to 'Tav' ("from A to Z").
תמים תהיה, whole-hearted to the extent that you will not even try and gain information
about future events except through an authentic prophet.
