Psalm 23

Psalm 19. In particular, versus 7-14: “ The law of Jehovah is perfect, bringing back the soul. The reminder of Jehovah is trustworthy, making the inexperienced one wise. The orders from Jehovah are upright, causing the heart to rejoice; The commandment of Jehovah is clean, making the eyes shine. The fear of Jehovah is pure, standing forever. The judicial decisions of Jehovah are true; they have proved altogether righteous. They are more to be desired than gold, yes, than much refined gold; And sweeter than honey and the flowing honey of the combs. Also, your own servant has been warned by them; In the keeping of them there is a large reward. Mistakes—who can discern? From concealed sins pronounce me innocent. Also from presumptuous acts hold your servant back; Do not let them dominate me. In that case I shall be complete, And I shall have remained innocent from much transgression. Let the sayings of my mouth and the meditation of my heart become pleasurable before you, O Jehovah my Rock and my Redeemer”.

Psalm 91 He who dwells in the shelter of the Most High will rest in the shadow of the Almighty. I will say of the Lord, "He is my refuge and my fortress, my God, in whom I trust." Surely he will save you from the fowler's snare and from the deadly pestilence. He will cover you with his feathers and under his wings you will find refuge; his faithfulness will be your shield and rampart. You will not fear the terror of night, nor the arrow that flies by day, nor the pestilence that stalks in the darkness, not the plague that destroys at midday. A thousand may fall at your side, ten thousand at your right hand, but it will not come near you. You will only observe with your eyes and see the punishment of the wicked. If you make the Most High your dwelling - even the Lord, who is my refuge - then no harm will befall you, no disaster will come near your tent. For he will command his angels concerning you to guard you in all your ways; they will lift you up in their hands, so that you will not strike your foot against a stone. You will tread upon the lion and the cobra; you will trample the great lion and the serpent. "Because he loves me," says the Lord, "I will rescue him; I will protect him, for he acknowledges my name. He will call upon me, and I will answer him; I will be with him in trouble, I will deliver him and honor him. With long life will I satisfy him and show him my salvation."

psalms 83:18: "that people may know that you, whose name is Jehovah, you alone are the Most High over all the earth."

Always Psalm 23. It's like a mantra with me. Whenever I'm in a dangerous or scary situation, I just repeat it over and over. I know it by heart.
