He made a pit - The allusion here is undoubtedly to a method of hunting wild beasts which was common in ancient times. It consists in digging a pit-fall, and covering it over with brush and grass so as to deceive the animals, and then enclosing them and driving them into it. See the notes at Isaiah 24:17.

And digged it - And hollowed it out so as to be large enough to contain his prey, and so deep that he could not escape if he fell into it. The idea is, that the enemy here referred to had laid a secret and artful plan to destroy others. He meant that they should not be aware of his plan until the mischief came suddenly upon them. He was preparing to ruin them, and supposed that he was certain of his prey.

And is fallen into the ditch which he made - Into the pit-fall which he had constructed for others; as if a man who had made a pit-fall for wild beasts had himself fallen into it, and could not extricate himself. That is, he had been snared in his own devices; his cunning had recoiled on himself, and instead of bringing ruin on others he had only managed to bring it on himself. See this sentiment illustrated in the notes at Job 5:13. A remarkable instance of the kind may be found in Esther (Esther 5-7), in the case of Haman. Indeed, such things are not uncommon in the world, where the cunning and the crafty are involved in the consequences of their own plans, and are taken in meshes from which they cannot free themselves. A straightforward course is easy, and men are safe in it; but it requires more skill than most men are endowed with to manage a crooked and crafty policy safely, or so as to be safe themselves in pursuing such a course. A spider will weave a web for flies with no danger to himself, for he is made for that, and acts as if he understood all the intricacies of his own web, and may move safely over it in every direction; but man was made to accomplish his purposes in an open and upright way, not by fraud and deceit; hence, when he undertakes a tortuous and crooked course - a plan of secret and scheming policy - in order to ruin others, it often becomes unmanageable by his own skill, or is suddenly sprung upon himself. No one can overvalue a straightforward course in its influence on our ultimate happiness; no one can overestimate the guilt and danger of a crooked and secret policy in devising plans of evil.

He made a pit - He determined the destruction of David. He laid his plans with much artifice; he executed them with zeal and diligence; and when he had, as he supposed, the grave of David digged, he fell into it himself! The metaphor is taken from pits dug in the earth, and slightly covered over with reeds &c. so as not to be discerned from the solid ground; but the animal steps on them, the surface breaks, and he falls into the pit and is taken. "All the world agrees to acknowledge the equity of that sentence, which inflicts upon the guilty the punishment intended by them for the innocent." - Horne.

He made a pit and digged it,.... That is, he digged a pit, and made it very large and capacious, to answer his purposes;

and is fallen into the ditch which he made; so it is said of the Heathen, Psalm 9:15; and is exemplified in the case of Haman, who was hanged upon the gallows he had built for Mordecai. Kimchi explains this of Saul's falling upon his own sword, and dying by it, which he drew against David; phrase is proverbial, Proverbs 26:27; the sense of this and the above figurative expressions is literally and properly given in Psalm 7:16.

He made a pit, and digged it, and is fallen into the ditch which he made.

He made a pit: Heb. He hath digged a pit

15, 16. 1Sa 18:17; 31:2 illustrate the statement whether alluded to or not. These verses are expository of Ps 7:14, showing how the devices of the wicked end in disappointment, falsifying their expectations.

7:10-17 David is confident that he shall find God his powerful Saviour. The destruction of sinners may be prevented by their conversion; for it is threatened, If he turn not from his evil way, let him expect it will be his ruin. But amidst the threatenings of wrath, we have a gracious offer of mercy. God gives sinners warning of their danger, and space to repent, and prevent it. He is slow to punish, and long-suffering to us-ward, not willing that any should perish. The sinner is described, ver. 14-16, as taking more pains to ruin his soul than, if directed aright, would save it. This is true, in a sense, of all sinners. Let us look to the Saviour under all our trials. Blessed Lord, give us grace to look to thee in the path of tribulation, going before thy church and people, and marking the way by thine own spotless example. Under all the persecutions which in our lesser trials mark our way, let the looking to Jesus animate our minds and comfort our hearts.
