6 Be strong and of a good courage, fear not, nor be afraid of them: for the Lord thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.
English Standard Version
6 Be strong and courageous. Do not fear or be in dread of them, for it is the Lord your God who goes with you. He will not leave you or forsake you."
6 "Be strong. Take courage. Don't be intimidated. Don't give them a second thought because God, your God, is striding ahead of you. He's right there with you. He won't let you down; he won't leave you."
New King James Version
6 Be strong and of good courage, do not fear nor be afraid of them; for the Lord your God, He is the One who goes with you. He will not leave you nor forsake you."
New Living Translation
6 So be strong and courageous! Do not be afraid and do not panic before them. For the Lord your God will personally go ahead of you. He will neither fail you nor abandon you."
Moses assures Israel of the constant presence of God with them. This is applied by the apostle to all God's spiritual Israel, to encourage their faith and hope; unto us is this gospel preached, as well as unto them; he will never fail thee, nor forsake thee, Hebrews 13:5. Moses commends Joshua to them for a leader; one whose wisdom, and courage, and affection they had long known; one whom God had appointed to be their leader; and therefore would own and bless. Joshua is well pleased to be admonished by Moses to be strong and of good courage. Those shall speed well, who have God with them; therefore they ought to be of good courage. Through God let us do valiantly, for through him we shall do victoriously; if we resist the devil, he will flee from us.
