Psalm 91:1-16 (HCSB)
1 The one who lives under the protection of the Most High dwells in the shadow of the Almighty.
2 I will say to the LORD, “My refuge and my fortress, my God, in whom I trust.”
3 He Himself will deliver you from the hunter’s net, from the destructive plague.
4 He will cover you with His feathers; you will take refuge under His wings. His faithfulness will be a protective shield.
5 You will not fear the terror of the night, the arrow that flies by day,
6 the plague that stalks in darkness, or the pestilence that ravages at noon.
7 Though a thousand fall at your side and ten thousand at your right hand, the pestilence will not reach you.
8 You will only see it with your eyes and witness the punishment of the wicked.
9 Because you have made the LORD—my refuge, the Most High—your dwelling place,
10 no harm will come to you; no plague will come near your tent.
11 For He will give His angels orders concerning you, to protect you in all your ways.
12 They will support you with their hands so that you will not strike your foot against a stone.
13 You will tread on the lion and the cobra; you will trample the young lion and the serpent.
14 Because he is lovingly devoted to Me, I will deliver him; I will protect him because he knows My name.
15 When he calls out to Me, I will answer him; I will be with him in trouble. I will rescue him and give him honor.
16 I will satisfy him with a long life and show him My salvation.

Dwellers are those who abide permanently or for a time in a place. A dwelling place is where someone lives, in biblical times either a tent as seen in Genesis 25:27, a house in 2 Samuel 7:2, or the territory in which one lives like in Genesis 36:40,43.
The Old Testament repeatedly promises that those who keep the covenant of God will dwell in safety-these are the dwellers in God, not so much of a physical dwelling but more of a spiritual state, a spiritual abiding or hiding oneself in God.
Proverbs 18:10 calls the Lord a strong tower where the righteous take refuge and find security: this is an intentional action on the believer’s part to hide in the Lord.
The dwelling place of the Lord is a secret place where we hide under His shadow from every attack of the enemy. As we dwell in God, Psalm 27:5 says He will conceal us in His shelter in the day of adversity.
Where do you shelter from the storms of life? When fear arises, do you run out or run into the secret place of God? To take cover under His tent? Where do you seek protection?
A hiding place, a secret hiding place is where you take shelter and plan your defensive attack and defeat of the enemy, God is the hiding place according to Psalm 32:7, within Him do you find protection in the day of adversity.
Sometimes, our nights are filled with terror and all kinds of arrows are shot at us in the day real or figuratively but when we dwell in God, they neither intimidate nor harm us.
Regardless of the dangers we face daily, and we can see through the passage that there is no shortage of dangers, even then, God covers His own, especially the dwellers with His faithfulness.
We will do well to study the word of God as prescribed in 2 Timothy 2:15 as Satan knows the Scriptures also. He quoted Psalm 91:11–12 when he tempted Jesus in the desert in Matthew 4:6, only misapplying it for his evil purposes.
This is not to say we should intentionally put ourselves in unnecessary danger because we “think” the Lord will deliver us, like Philip Bracey of Los Angeles who on February 27, 2017, jumped into the lion exhibit at the Los Angeles Zoo because he was daring to be a Daniel, believing that God will shut the Lions’ mouth but was immediately mauled by the beasts. Jesus said, “thou shall not tempt the Lord your God” in Matthew 4:7.
A dweller in God don’t go seeking and courting danger, they run into the Lord for protection, security and victory says verse 4.
God protects those who trust and dwell in Him from all harm. If you don’t yet trust God to dwell securely in Him, let me encourage you to do so now, so that no harm can befall you, especially in the unstable, unsafe and uncertain atmosphere of society.
Call upon the name of the Lord, the shelter, strong tower and refuge encourage verse 15, and I will answer you, promises the Lord, even as He promises to satisfy all your needs including long life, that is eternal life by His salvation. Be a dweller in God.
Shalom
