The Psalm this morning at St. Mary's was Psalm 17. In particular I noticed verse 3. In the translation we heard it went:
Weigh my heart, summon me by night"Melt me down...find no impurity..." What did I think of?.... That the Psalms were written before the time of Archimedes (True, BTW).
melt me down, you will find no impurity in me.
