Hebrews 13:6 - Matthew Poole's English Annotations on the Holy Bible

So that we may boldly say; upon the account of which promise of God all the true subjects of Christ's kingdom, together with the apostle, may with an undaunted boldness of heart, above all fears and doubtings, and with a daring confidence, professing that which they believe, nor staggering, nor shrinking, nor being ashamed of their faith, but openly owning it to all the world, own that The Lord is my helper; the Lord in the infiniteness of his power, wisdom, and goodness, is a real, present, universal, and permanent help against all trouble, and for all supplies in all cases, and at all times, to every one of them. They may say as Moses, Exodus 18:4; as David, Psalms 27:9, Psalms 40:17 56:4,11 118:6. And I will not fear what man shall do unto me: and therefore faith expelleth fearfulness of, and introduceth fearlessness of, any created evils incident to a believer; and of which man may be an instrument inflicting, Psalms 46:2,3. Implying in it an unshaken settledness of mind, judgment, and thoughts on God's help, a fixed frame of heart, without tumultuous passions or perturbations, with an unmovable resolution to keep close to God and his word both in word and deed, amidst all oppositions and persecutions of men for it.
