We are almost at the end of Psalm 119. Let us ask who wrote Psalm 119 ? The internet suggests David, Ezra or Daniel as the possible author. Upon reading verses 161 to 168, my guess is King David wrote it based on Bible's description of David as a man after God's own heart.
Do you have the Bible within reach from your computer or cell phone ? I hope you do. God bless you.
By the way i just remembered most cell phones have the Bible in it.
