Psalms 71:8

David prays that he might never be made ashamed of dependence upon God. With this petition every true believer may come boldly to the throne of grace. The gracious care of Divine providence in our birth and infancy, should engage us to early piety. He that was our Help from our birth, ought to be our Hope from our youth. Let none expect ease or comfort from the world. Those who love the Lord, often are hated and persecuted; men wondered at for their principles and conduct; but the Lord has been their strong refuge. The faithful servants of God may be assured that he will not cast them off in old age, nor forsake them when their strength fails.

Let my mouth be filled with thy praise and with thy honour all the day. What a blessed mouthful! A man never grows nauseated though the flavour of it be all day in his mouth. God's bread is always in our mouths, so should his praise be. He fills us with good; let us be also filled with gratitude. This would leave no room for murmuring or backbiting; therefore, may we well join with holy David in this sacred wish.
