Psalm 116:8-12 KJV
"8 For thou hast delivered my soul from death, mine eyes from tears, and my feet from falling.
9 I will walk before the Lord in the land of the living.
10 I believed, therefore have I spoken: I was greatly afflicted:
11 I said in my haste, All men are liars.
12 What shall I render unto the Lord for all his benefits toward me?"
Psalm 116:8-12 NASB
"For You have rescued my soul from death, My eyes from tears, My feet from stumbling. 9 I shall walk before the Lord In the [e]land of the living. 10 I believed when I said, “I am greatly afflicted.” 11 I said in my alarm, “All men are liars.”
12 What shall I render to the Lord For all His benefits [f]toward me?"
Psalm 116:8-12 CEV
"You, Lord, have saved my life from death, my eyes from tears, my feet from stumbling. 9 Now I will walk at your side in this land of the living. 10 I was faithful to you when I was suffering, 11 though in my confusion I said, “I can’t trust anyone!”
12 What must I give you, Lord, for being so good to me?"
===================================
When vpw/twi bases a docrrine on EXACTLY ONE VERSE (or less), I'm highly suspicious it may have meant nothing of the kind. I see no reason to think this verse is outlining a rule that says "All men are liars." Looks to me like that was the state of mind of the psalmist at the moment he said that, whether true or not.
