Concise Bible Commentary
David said not, What magnificent thing shall I do now? or, What pleasant thing? but, What pious thing? that he might have the comfort and benefit of that sacred oracle. Let us bring the ark to us, that it 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.
