E Davi deu a Ornã por aquele lugar o peso de seiscentos siclos de ouro.
Rav Hirsch
מכל שבטיכם, von allen und für alle, und hatten daher alle Stämme bei dem dereinstigen Erwerb dieser von Gott erwählten Stelle zum einzigen Nationalheiligtum für alle zu konkurrieren. Die durch Innehalten der Pest und durch das Prophetenwort Gads bezeichnete Gottesstätte in Jerusalem erwarb David von dem bisherigen Besitzer für sechshundert Schekel, wozu er für sich und Juda fünfzig gab und so von jedem der zwölf Stämme fünfzig erhob (vergl. Sam. II. 24, 24 und Chron. I. 21, 25 ספרי z. St. – siehe Sebachim 116b).

unless you remove the blind and the lame – Yonatan translates this phrase as ‘unless you remove the sinners and the wicked who say that David will not come here.’ We find in the rabbinic literature that the men of Yevus said to Avraham ‘make a covenant with us that your descendants will not inherit the city of Yevus, and we will sell you the Machpela cave. He did so, and the men of Yevus made bronze idols upon which they wrote the oath and then placed in the city square. When Israel came into the land they were unable to enter the city because of the oath, as it says “And the children of Benjamin did not drive out the Jebusites that inhabited Jerusalem…” (Shoftim 1:21) When David became king he wanted to enter there but they did not allow him to, as it says “…you shall not come here…” (Shmuel II 5:6) They said to him ‘you are not able until you remove these idols upon which the oath and covenant are written’ as it says “…unless you remove the blind and the lame…” (ibid.) which are the idols that have eyes but cannot see, ears but cannot hear, legs but cannot walk - those which David’s soul loathes and which he hates to hear of them and those that worship them, as it says “Therefore they say, ‘The blind and the lame shall not come into the house.’” (Shmuel II 5:8) David said to his men ‘who ever goes up first and removes the idols will be my chief officer. Yoav went up and became his chief officer, as it says “…and Yoav the son of Zeruiah ascended first and became a chief.” (Divre HaYamim I 11:6) Afterward David purchased the city of Yevus on behalf of all Israel with gold, with an eternal deed as an everlasting possession for six hundred gold pieces, as it says “And David gave to Ornan for the place shekels of gold weighing six hundred.” (Divre HaYamim I 21:25) They further said that these two idols were at the top of the tower called Tzinor (see Shmuel II 5:8). One was blind in reference to Yitzchak and the other lame in reference to Yaakov and in their mouth was the oath which Avraham swore to Avimelech, as it says “And now, swear to me here by God, that you will not lie to me or to my son or to my grandson…” (Bereshit 21:23) Therefor Israel did not conquer it when they conquered Jerusalem because the grandson of Avimelech was still alive. But in the days of David he had already died and the oath was nullified. The wise man R’ Avraham ibn Ezra explained the phrase “…unless you remove (hisircha)…” (Shmuel II 5:6) as hasir that it to say turn towards, meaning even if the blind and the lame turn to fight you then they will keep you out. That you will not come in here because the tower is so strong and we do not fear you in battle.
Rabbeinu Bahya
כי אם במקום אשר יבחר ה' באחד שבטיך, “except in the place which the Lord will choose amongst one of your tribes.” The Torah speaks in general terms without specifying in whose tribal territory this place will be located. It turned out to be the territory of Binyamin (Zevachim 54). In verse 8 in our chapter the wording had been: מכל שבטיכם, “from among all your tribes.” How can we reconcile these two verses? When David purchased the threshing ground of Ornan the Jebusite, the site on which the Temple would be built, he raised the money for this from all the tribes, a total equivalent to six hundred shekel (in) gold (Chronicles I 21,25). On the other hand, the amount paid for that site described in Samuel II 24,24 was only 50 shekel silver. How do we account for this contradiction? The answer is that the 600 shekels must be divided into 12, (the number of tribes). The Book of Samuel informs us that each tribe contributed an amount of 50 shekel to the purchase of the site on which the Temple was built. The reason the number 50 is mentioned at all is that David personally handed over the share of the tribe of Yehudah consisting of 50 shekels.
