Thy Word is a lamp unto my feet, and a light unto my path.

Thy Word is a lamp unto my feet, and a light unto my path. I have sworn, and I will perform it, that I will keep thy righteous judgments.  I am afflicted very much; quicken me, O Lord, according unto thy Word. Accept, I beseech thee, the freewill offerings of my mouth, O Lord, and teach me thy judgments. My soul is continually in my hand, yet do I not forget thy Law. The wicked have laid a snare for me, yet I erred not from thy precepts. Thy Testimonies have I taken as a heritage forever, for they are the rejoicing of my heart. I have inclined mine heart to perform thy Statutes always, even unto the end.  Psalms 119:105-112 (KJV)

Help LORD, for the godly man ceases, for the faithful fail from among the children of men. They speak vanity every one with his neighbor, with flattering lips and with a double heart do they speak.  The LORD shall cut off all flattering lips, and the tongue that speaks proud things who have said, with our tongue will we prevail, our lips are our own, who is lord over us?

The oppression of the poor, for the sighing of the needy, now will I arise, saith the LORD; I will set him in safety from him that puffs at him. The Words of the LORD are pure Words, as silver tried in a furnace of earth, purified seven times.

Thou shalt keep them, O LORD thou shalt preserve them from this generation forever. The wicked walk on every side when the vilest men are exalted.  Psalms 12:1-8 (KJV)

Question:

Who was King David’s defense?

And David spake unto the LORD the words of this song in the day that the LORD had delivered him out of the hand of all his enemies, and out of the hand of Saul:
 

And he said, The LORD is my Rock, and my Fortress, and my Deliverer; The God of my Rock; in Him will I trust, he is my Shield, and the Horn of my Salvation, my High Tower, and my Refuge, my Saviour; thou savest me from violence. I will call on the LORD, who is Worthy to be praised, so shall I be saved from mine enemies. II Samuel 22:1-4

(KJV)
