4 He will cover you with his feathers. Under his wings you will take refuge. His faithfulness is your shield and rampart.

He shall protect thee with his wings. This figure, which is employed in other parts of Scripture, is one which beautifully expresses the singularly tender care with which God watches over our safety. When we consider the majesty of God, there is nothing which would suggest a likeness such as is here drawn between him and the hen or other birds, who spread their wings over their young ones to cherish and protect them. But, in accommodation to our infirmity, he does not scruple to descend, as it were, from the heavenly glory which belongs to him, and to encourage us to approach him under so humble a similitude. Since he condescends in such a gracious manner to our weakness, surely there is nothing to prevent us from coming to him with the greatest freedom. By the truth of God, which, the Psalmist says, would be his shield and buckler, we must understand God's faithfulness, as never deserting his people in the time of their need; still we cannot doubt that he had in his eye the Divine promises, for it is only by looking to these that any can venture to cast themselves upon the protection of God. As, without the word, we cannot come to the enjoyment of that Divine mercy of which the Psalmist had already spoken, he now comes forward himself to bear witness in behalf of it. Formerly, under the comparison of a fortress, he had taught that by trusting in God we shall enjoy safety and security; now he compares God to a shield, intimating that he will come between us and all our enemies to preserve us from their attacks.
He shall cover thee with his feathers - As the parent bird protects its young. See the notes at Psalm 17:8. Compare Deuteronomy 32:11. "His truth." His unfailing promise; the certainty that what he has promised to do he will perform.
Shall be thy shield and buckler - literally, "Shield and buckler is his truth." The meaning is, that his pledge or promise would be unto them as the shield of the soldier is to him in battle. Compare Psalm 35:2. The word rendered "buckler" is derived from the verb "to surround," and is given to the defensive armor here referred to, because it "surrounds," and thus "protects" a person. It may apply to a coat of mail.
He shall cover thee with his feathers - He shall act towards thee as the hen does to her brood, - take thee under his wings when birds of prey appear, and also shelter thee from chilling blasts. This is a frequent metaphor in the sacred writings; see Psalm 17:8 (note), Psalm 57:1 (note), Psalm 61:4 (note), and the notes on them. The Septuagint has Εν τοις μεταφρενοις αυτου επισκιασει σοι· He will overshadow thee between his shoulders; alluding to the custom of parents carrying their weak or sick children on their backs, and having them covered even there with a mantle. Thus the Lord is represented carrying the Israelites in the wilderness. See Deuteronomy 32:11-12 (note), where the metaphor is taken from the eagle.
His truth shall be thy shield and buckler - His revelation; his Bible. That truth contains promises for all times and circumstances; and these will be invariably fulfilled to him that trusts in the Lord. The fulfillment of a promise relative to defense and support is to the soul what the best shield is to the body.
He shall cover thee with his feathers, and under his wings shalt thou trust: his (d) truth [shall be thy] shield and buckler.
(d) That is, his faithful keeping of promises to help you in your need.
He shall cover thee with his feathers,.... As birds do their young, who cannot cover themselves: this they do from a tender regard to them, whereby they both keep them warm, and protect them from those that would hurt them: this represents the helpless state of the children of God, who are, like to young birds, weak and unable to defend themselves: the tender regard of God unto them, as the eagle and other birds have to their young; see Deuteronomy 32:11 and the warmth and comforts souls have, as well as protection, under his powerful and gracious presence; he comforts them under their tribulations, as well as defends them from their enemies:
and under his wings shalt thou trust; See Gill on Psalm 91:1 and the passages there referred to; the same metaphor is continued:
his truth shall be thy shield and buckler; his faithfulness, which is engaged to keep and preserve his saints safe to his kingdom and glory, 1-Corinthians 1:8, his Son, who is "truth" itself, John 14:6, and whose person, blood, righteousness, and salvation, are as a shield and buckler all around the saints, to secure them from ruin and destruction; and are the shield which faith lays hold on, and makes use of, against the temptation, of Satan; see Psalm 84:11, the word of God also, which is truth, John 17:19, every promise in it, and doctrine of it, is as a shield and buckler to strengthen, support, and secure the faith of his people, Proverbs 30:5.
For the first figure compare Deuteronomy 32:11; Matthew 23:37.
buckler--literally, "surrounding"--that is, a kind of shield covering all over.
