9 Because you have made Yahweh your refuge,
and the Most High your dwelling place, 10 no evil shall happen to you,
neither shall any plague come near your dwelling. 11 For he will put his angels in charge of you,
to guard you in all your ways. 12 They will bear you up in their hands,
so that you won’t dash your foot against a stone. 13 You will tread on the lion and cobra.
You will trample the young lion and the serpent underfoot. 14 “Because he has set his love on me, therefore I will deliver him.
I will set him on high, because he has known my name. 15 He will call on me, and I will answer him.
I will be with him in trouble.
I will deliver him, and honor him. 16 I will satisfy him with long life,
and show him my salvation.”

Matthew Henry's Commentary on Psalm 91:9-16

Commentary on Psalm 91:9-16

(Read Psalm 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.
