Deuteronomy 31:8 AMPC assuredly says :
” It is the Lord Who goes before you; He will [march] with you; He will not fail you or let you go or forsake you; [let there be no cowardice or flinching, but] fear not, neither become broken [in spirit–depressed, dismayed, and unnerved with alarm].”

Then,  Isaiah 43:1-5 AMPC says:
” BUT NOW [in spite of past judgments for Israel’s sins], thus says the Lord, He Who created you, O Jacob, and He Who formed you, O Israel: Fear not, for I have redeemed you [ransomed you by paying a price instead of leaving you captives]; I have called you by your name; you are Mine. [2] When you pass through the waters, I will be with you, and through the rivers, they will not overwhelm you. When you walk through the fire, you will not be burned or scorched, nor will the flame kindle upon you. [3] For I am the Lord your God, the Holy One of Israel, your Savior; I give Egypt [to the Babylonians] for your ransom, Ethiopia and Seba [a province of Ethiopia] in exchange [for your release]. [4] Because you are precious in My sight and honored, and because I love you, I will give men in return for you and peoples in exchange for your life. [5] Fear not, for I am with you; I will bring your offspring from the east [where they are dispersed] and gather you from the west. [Acts 18:10.]”

” HE WHO dwells in the secret place of the Most High shall remain stable and fixed under the shadow of the Almighty [Whose power no foe can withstand].  I will say of the Lord, He is my Refuge and my Fortress, my God; on Him I lean and rely, and in Him I [confidently] trust!  For [then] He will deliver you from the snare of the fowler and from the deadly pestilence.  [Then] He will cover you with His pinions, and under His wings shall you trust and find refuge; His truth and His faithfulness are a shield and a buckler.  You shall not be afraid of the terror of the night, nor of the arrow (the evil plots and slanders of the wicked) that flies by day, Nor of the pestilence that stalks in darkness, nor of the destruction and sudden death that surprise and lay waste at noonday.  A thousand may fall at your side, and ten thousand at your right hand, but it shall not come near you. Only a spectator shall you be [yourself inaccessible in the secret place of the Most High] as you witness the reward of the wicked. Because you have made the Lord your refuge, and the Most High your dwelling place, [Ps. 91:1, 14.]  There shall no evil befall you, nor any plague or calamity come near your tent.”( Psalms 91:1-10 AMPC).

” If you [really] love Me, you will keep (obey) My commands.  And I will ask the Father, and He will give you another Comforter (Counselor, Helper, Intercessor, Advocate, Strengthener, and Standby), that He may remain with you forever–  The Spirit of Truth, Whom the world cannot receive (welcome, take to its heart), because it does not see Him or know and recognize Him. But you know and recognize Him, for He lives with you [constantly] and will be in you. I will not leave you as orphans [comfortless, desolate, bereaved, forlorn, helpless]; I will come [back] to you.”(John 14:15-18 AMPC).

” Let your character or moral disposition be free from love of money [including greed, avarice, lust, and craving for earthly possessions] and be satisfied with your present [circumstances and with what you have]; for He [God] Himself has said, I will not in any way fail you nor give you up nor leave you without support. [I will] not, [I will] not, [I will] not in any degree leave you helpless nor forsake nor let [you] down (relax My hold on you)! [Assuredly not!] [Josh. 1:5.]  So we take comfort and are encouraged and confidently and boldly say, The Lord is my Helper; I will not be seized with alarm [I will not fear or dread or be terrified]. What can man do to me? [Ps. 27:1;118:6.]” (Hebrews 13:5-6 AMPC).

” Now to Him Who is able to keep you without stumbling or slipping or falling, and to present [you] unblemished (blameless and faultless) before the presence of His glory in triumphant joy and exultation [with unspeakable, ecstatic delight]– To the one only God, our Savior through Jesus Christ our Lord, be glory (splendor), majesty, might and dominion, and power and authority, before all time and now and forever (unto all the ages of eternity). Amen (so be it).”[ Jude 1:24-25 AMPC].
