Thou shalt tread upon the lion and adder - Thou shalt be safe among dangers, as if the rage of the lion were restrained, and he became like a lamb, and as if the poisonous tooth of the serpent were extracted. Compare Mark 16:18. The word used here to denote the "lion" is a poetic term, not employed in prose. The word rendered "adder" is, in the margin, asp. The Hebrew word - פתן pethen - commonly means viper, asp, or adder. See Job 20:14, note; Job 20:16, note; compare Psalm 58:4; Isaiah 11:8. It may be applied to any venomous serpent.

The young lion - The "young" lion is mentioned as particularly fierce and violent. See Psalm 17:12.

And the dragon ... - Hebrew, תנין tannı̂yn. See Psalm 74:13, note; Job 7:12, note; Isaiah 27:1, note. In Exodus 7:9-10, Exodus 7:12, the word is rendered serpent (and serpents); in Genesis 1:21; and Job 7:12; whale (and whales); in Deuteronomy 32:33; Nehemiah 2:13; Psalm 74:13; Psalm 148:7; Isaiah 27:1; Isaiah 51:9; Jeremiah 51:34, as here, dragon (and dragons); in Lamentations 4:3, sea monsters. The word does not occur elsewhere. It would perhaps properly denote a sea monster; yet it may be applied to a serpent. Thus applied, it would denote a serpent of the largest and most dangerous kind; and the idea is, that he who trusted in God would be safe amidst the most fearful dangers, as if he should walk safely amidst venomous serpents.

Thou shalt tread upon the lion and adder - Even the king of the forest shall not be able to injure thee; should one of these attack thee, the angels whom God sends will give thee an easy victory over him. And even the asp, (פתן pethen), one of the most venomous of serpents, shall not be able to injure thee.

The asp is a very small serpent, and peculiar to Egypt and Libya. Its poison kills without the possibility of a remedy. Those who are bitten by it die in about from three to eight hours; and it is said they die by sleep, without any kind of pain. Lord Bacon says the asp is less painful than all the other instruments of death. He supposes it to have an affinity to opium, but to be less disagreeable in its operation. It was probably an this account that Cleopatra, queen of Egypt, chose to die by the asp, as she was determined to prevent the designs of Augustus, who intended to have carried her captive to Rome to grace his triumph.

The dragon shalt thou trample - The תנין tannin, which we translate dragon, means often any large aquatic animal; and perhaps here the crocodile or alligator.

Thou shalt tread upon the lion and adder,.... Or be unhurt by such savage and poisonous creatures; as the Israelites, when they travelled through the wilderness, in which were serpents and scorpions; and many of the servants of God have been delivered from them, or have slain them, as Samson, David, and Daniel; and so Christ was among the wild beasts in the wilderness, and yet not touched or hurt by them; and his disciples had power given them by him to tread on serpents and scorpions, and to take up serpents, without receiving any damage from them; and when a viper fastened on the hand of the Apostle Paul, he shook it off, without being hurt by it; see Mark 1:13, Acts 28:5, it may be understood figuratively of Satan, who, for his voraciousness and cruelty, is compared to a lion; and, for his craft and subtlety, to a serpent, 1 Peter 5:8,

the young lion and the dragon shalt thou trample underfoot; which also may be understood of the great dragon, the old serpent, called the devil and Satan; whom Christ trampled under his feet when he hung on the cross, and spoiled him and his principalities and powers; and who, in a short time, will be bruised under the feet of his people, as he has been already by the seed of the woman, Genesis 3:15.

Thou shalt tread upon the lion and adder: the {h} young lion and the dragon shalt thou trample under feet.

(h) You will not only be preserved from all evil, but overcome it whether it is secret or open.

91:13 The lion - Shall lie prostrate at thy feet, and thou shalt securely put thy feet upon his neck. Dragon - By which he understands all pernicious creatures, though never so strong, and all sorts of enemies.

adder: or, asp

13. Even the fiercest, strongest, and most insidious animals may be trampled on with impunity.

91:9-16 Whatever happens, nothing shall hurt the believer; though trouble and affliction befal, it shall come, not for his hurt, but for good, though for the present it be not joyous but grievous. Those who rightly know God, will set their love upon him. They by prayer constantly call upon him. His promise is, that he will in due time deliver the believer out of trouble, and in the mean time be with him in trouble. The Lord will manage all his worldly concerns, and preserve his life on earth, so long as it shall be good for him. For encouragement in this he looks unto Jesus. He shall live long enough; till he has done the work he was sent into this world for, and is ready for heaven. Who would wish to live a day longer than God has some work to do, either by him or upon him? A man may die young, yet be satisfied with living. But a wicked man is not satisfied even with long life. At length the believer's conflict ends; he has done for ever with trouble, sin, and temptation.
