That they might observe his statutes, and keep his laws - The end - the design - of all this was that they might be an obedient people. This was the purpose of all his interventions in their behalf; and their obligation to obedience was enforced and measured by what he had done. The same is true in regard to his people now.
Praise ye the Lord - Hebrew, Hallelu-jah. See Psalm 104:35.

That they might observe his statutes - That they might be properly instructed, and properly disciplined. This is the end proposed by Divine revelation: men are to be made wise unto salvation, and then to be brought under the yoke of obedience. He who is not conformed to God's word shall not enter into Christ's kingdom.

That they might (z) observe his statutes, and keep his laws. Praise ye the LORD.
(z) This is the reason why God preserves his Church, because they should worship and call on him in this world.

That they might observe his statutes, and keep his laws,.... All this the Lord did for them, to engage them by his goodness to them to observe the statutes he appointed them, and the laws he gave them; the contrary to which the Canaanites had done, which caused him to cast them out of the land; but on these his people he heaped benefits, thereby to influence them to a cheerful obedience to his will; and this was all he required of them, and the least that they could do, being so highly favoured by him. And this is the end of our spiritual and eternal redemption by Christ, and of our effectual calling by his grace and Spirit, that we be zealous of good works; live unto righteousness, live to him that died for us; glorify him with our bodies and spirits, which are his; and be holy in all manner of conversation.
Praise ye the Lord, all the Israelites ought to have done so, upon the remembrance of the manifold instances of the divine goodness to them, recorded in this psalm; and so the spiritual Israel of God ought to praise him for their redemption by Christ, out of a worse than Egyptian bondage, the bondage of sin, Satan, and the law; and for their calling into liberty, and to marvellous light; for their meetness for heaven, and right unto it; they should praise him now with joyful lips, as they will in the other world to all eternity.
