John Gill's Bible Commentary Ver. 5. So David gathered all Israel together , etc.] The principal of them, even 30,000 select men, ( 2 Samuel 6:1) from Shihor of Egypt ; or the Nile of Egypt, as the Targum and other Jewish writers, called Shihor from the blackness of its water, (see Jeremiah 2:18) though some think the river Rhinocurura is meant, which both lay to the south of the land of Israel: even unto the entering of Hamath ; which the Targum interprets of Antiochia, which lay to the north of the land; so that this collection of the people was made from south to north, the extreme borders of the land: to bring the ark of God from Kirjathjearim ; where it then was, and had been a long time, (see 1 Samuel 7:1), from hence to the end of the chapter the account is the same with ( 2 Samuel 6:1-11), see the notes there; what little variations there are, are there observed.
Matthew Henry Commentary
Verses 1-5 - David said not, What magnificent thing shall I do now? or, What pleasant thing? but, What pious thing? that he might have the comfor and benefit of that sacred oracle. Let us bring the ark to us, that is may be a blessing to us. Those who honour God, profit themselves. It is the wisdom of those setting out in the world, to take God's ark with them. Those are likely to go on in the favour of God, who begin in the fear of God. (1Ch 13:6-14)
