The ark of God remained with the family of Obed-Edom in his house for three months

1 Chronicles 13:1-14
Let us bring the ark of our God back to us, for we did not inquire of[a] it[b] during the reign of Saul.” The whole assembly agreed to do this, because it seemed right to all the people.
So David assembled all Israel, from the Shihor River in Egypt to Lebo Hamath, to bring the ark of God from Kiriath Jearim. David and all Israel went to Baalah of Judah (Kiriath Jearim) to bring up from there the ark of God the Lord.
They moved the ark of God from Abinadab’s house on a new cart, with Uzzah and Ahio guiding it.
Then David was angry because the Lord’s wrath had broken out against Uzzah, and to this day that place is called Perez Uzzah.
David was afraid of God that day and asked, “How can I ever bring the ark of God to me?”  He did not take the ark to be with him in the City of David. Instead, he took it to the house of Obed-Edom the Gittite. The ark of God remained with the family of Obed-Edom in his house for three months, and the Lord blessed his household and everything he had.
In line with his purpose of outlining the religious history of the nation, the Chronicler assigns this event first place in the record of David's reign. In the actual point of time, it came somewhat later.
Why?
David is like the ark of the Lord may come with him in Jerusalem, but he did not know that the Ark could not be carried on the car, but it has to be carried by men on shoulder.
David was angry because he did not know the regulation of the Lord.

Three months the house of Obed-Edom is blessed by the Lord. So it is showing that living with the Lord is blessed.

神為何如此擊殺烏撒，大衛卻沒有求問神，只是問人，憑自己的意思做，雖然不見得是私心，而且沒有按照神定的規矩來遵行。約櫃不是貨物，是神同在的象徵。
掃羅把約櫃當護身符。不是人決定放在那裏，是由神來決定。不是挾上帝來成就自己的事。
約櫃不是被擄，是在外邦中宣示神的主權。
大衛認為有責任帶領以色列人建立信仰。過去用錯誤的方法服事神。可惜這次還是用非利士人的方法來移動約櫃。烏撒是利未人應該知道這件事錯誤，豈能因為烏撒扶約櫃，反而要大衛來感謝烏撒。
大衛可能想表示他愛神，這是把約櫃表示他敬畏神，同樣也是挾約櫃以令上帝的方法。只有神自己才是 建立神人關係的發動者及成全者。有些事不是人想做就可以做，即使是想敬畏神，明白神的心意，討神的喜悅。不要走在神的前面。告訴大衛：耶和華才是主。
對回歸的人而言，藉此事讓他們知道要依靠神來發動、成全。我們只有去明白神的心意，跟隨神的腳踪行。不是靠許多愛的主的行為來，顯示自己的愛主。

How?
No because of who am I, when I am with the Lord, God's blessing will be with me.
