He states that the Ark represents the full testimony and presence of Christ, and that the cart used by David represented the ways of the world. We need to not use the ways of the world to convey the presence and testimony of the Lord.
1 And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father’s name written in their foreheads.
22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
10 He shall build an house for my name; and he shall be my son, and I will be his father; and I will establish the throne of his kingdom over Israel for ever.
16 And David the king came and sat before the LORD, and said, Who am I, O LORD God, and what is mine house, that thou hast brought me hitherto? 17 And yet this was a small thing in thine eyes, O God; for thou hast also spoken of thy servant’s house for a great while to come, and hast regarded me according to the estate of a man of high degree, O LORD God. 18 What can David speak more to thee for the honour of thy servant? for thou knowest thy servant.
37 So he left there before the ark of the covenant of the LORD Asaph and his brethren, to minister before the ark continually, as every day’s work required:
1 So they brought the ark of God, and set it in the midst of the tent that David had pitched for it: and they offered burnt sacrifices and peace offerings before God. 2 And when David had made an end of offering the burnt offerings and the peace offerings, he blessed the people in the name of the LORD. 3 And he dealt to every one of Israel, both man and woman, to every one a loaf of bread, and a good piece of flesh, and a flagon of wine. 4 And he appointed certain of the Levites to minister before the ark of the LORD, and to record, and to thank and praise the LORD God of Israel:
25 So David, and the elders of Israel, and the captains over thousands, went to bring up the ark of the covenant of the LORD out of the house of Obededom with joy.
12 And said unto them, Ye are the chief of the fathers of the Levites: sanctify yourselves, both ye and your brethren, that ye may bring up the ark of the LORD God of Israel unto the place that I have prepared for it. 13 For because ye did it not at the first, the LORD our God made a breach upon us, for that we sought him not after the due order. 14 So the priests and the Levites sanctified themselves to bring up the ark of the LORD God of Israel. 15 And the children of the Levites bare the ark of God upon their shoulders with the staves thereon, as Moses commanded according to the word of the LORD.
1 And David made him houses in the city of David, and prepared a place for the ark of God, and pitched for it a tent. 2 Then David said, None ought to carry the ark of God but the Levites: for them hath the LORD chosen to carry the ark of God, and to minister unto him for ever. 3 And David gathered all Israel together to Jerusalem, to bring up the ark of the LORD unto his place, which he had prepared for it. 4 And David assembled the children of Aaron, and the Levites:
1 And David consulted with the captains of thousands and hundreds, and with every leader. 2 And David said unto all the congregation of Israel, If it seem good unto you, and that it be of the LORD our God, let us send abroad unto our brethren every where, that are left in all the land of Israel, and with them also to the priests and Levites which are in their cities and suburbs, that they may gather themselves unto us: 3 And let us bring again the ark of our God to us: for we enquired not at it in the days of Saul. 4 And all the congregation said that they would do so: for the thing was right in the eyes of all the people. 5 So David gathered all Israel together, from Shihor of Egypt even unto the entering of Hemath, to bring the ark of God from Kirjathjearim. 6 And David went up, and all Israel, to Baalah, that is, to Kirjathjearim, which belonged to Judah, to bring up thence the ark of God the LORD, that dwelleth between the cherubims, whose name is called on it. 7 And they carried the ark of God in a new cart out of the house of Abinadab: and Uzza and Ahio drave the cart. 8 And David and all Israel played before God with all their might, and with singing, and with harps, and with psalteries, and with timbrels, and with cymbals, and with trumpets.
9 And when they came unto the threshingfloor of Chidon, Uzza put forth his hand to hold the ark; for the oxen stumbled. 10 And the anger of the LORD was kindled against Uzza, and he smote him, because he put his hand to the ark: and there he died before God. 11 And David was displeased, because the LORD had made a breach upon Uzza: wherefore that place is called Perezuzza to this day. 12 And David was afraid of God that day, saying, How shall I bring the ark of God home to me? 13 So David brought not the ark home to himself to the city of David, but carried it aside into the house of Obededom the Gittite. 14 And the ark of God remained with the family of Obededom in his house three months. And the LORD blessed the house of Obededom, and all that he had.
