(10) There shall not be found among you anyone who passes his son or daughter through fire, a soothsayer, a diviner of [auspicious] times, one who interprets omens, or a sorcerer,(11) or a charmer, a pithom sorcerer, a yido'a sorcerer, or a necromancer. (12) For whoever does these things is an abomination to the Lord, and because of these abominations, the Lord, your God is driving them out from before you. (13) Be wholehearted/perfect with the Lord, your God.

There is a large letter "Taf", since if one goes wholeheartedly it is as if he has kept [the entire torah] from Aleph to Taf.

(9) These are the generations of Noah. Noah was a righteous man, wholehearted/ Perfect in his generation; Noah walked with God.

(27) And the boys grew; and Esau was a cunning hunter, a man of the field; and Jacob was a wholehearted/perfect man, dwelling in tents.

(1) And when Avraham was ninety nine years old, Hashem appeared to Avraham, and said to him: ‘I am God Almighty; walk before Me, and be wholehearted/perfect.

(15) And G-d said to Avraham "[As for] Sarai your wife, do not call her by the name Sarai (שרי), for Sarah (שרה) is her name. (16) I will bless her, and I will also give you a son through her. I will bless her, and she will be [a mother] of nations, kings of peoples will descend from her." (17) Avraham fell on his face and laughed (Unkelus: “laughed” = Chadi / חדי). He said in his heart: "Can a hundred year old man have children? Shall Sarah, who is ninety years old give birth?" (19) G-d said: "Indeed, your wife Sarah will bear you a son, and you will name him Yitzchok. I will establish My covenant with him as an eternal covenant to his descendants after him.

(9) They said to him, "Where is Sarah, your wife?" He said "Here, in the tent." (10) He said "I will return to you next year, and Sarah, your wife will have a son." Sarah was listening at the door of the tent, that was behind him. (11) Avraham and Sarah were old, well on in years. Sarah no longer had the way of women. (12) Sarah laughed to herself (Unkelus: “laughed” = Chayech) saying, "Now that I have withered, I shall again have delicate skin? And my husband is old.” (13) G-d said to Avraham, "Why did Sarah laugh saying, 'Can I really give birth when I am old?' (14) Is anything hidden from G-d? At the appointed time I will return to you, at this time of life, and Sarah will have a son." (15) Sarah denied it saying, "I did not laugh," for she was afraid. He said, "Not so, for you did laugh."

(2) And He said, "Please take your son, your only one, whom you love, Isaac, and go away to the land of Moriah and bring him up there for a burnt offering on one of the mountains, of which I will tell you."(3) And Abraham arose early in the morning, and he saddled his donkey, and he took his two young men with him and Isaac his son; and he split wood for a burnt offering, and he arose and went to the place of which God had told him.

"And…arose early:" He hastened to [perform] the commandment (Pes. 4a).

"He Saddled": He himself, and he did not command one of his servants, because love causes a disregard for the standard [of dignified conduct]. — [from Gen. Rabbah 55:8]

(Hashem called the Jewish people "complete") referring to Sinai, where they said "All that Hashem will say, we will do and we will listen."

Be wholehearted with the Lord, your God: Conduct yourself with Him with perfection and depend on Him, and do not inquire of the future; rather, accept whatever happens to you with [unadulterated] simplicity and then, you will be with Him and to His portion. — [Sifrei]
