Examine me, O LORD, and test me; cleanse my mind and my heart.
MIDRASH TEHILLIM
1.....(26.3) ...test me...
David said, Test me, O LORD, as You tested Abraham, of whom the verse - "...God tested Abraham..." Bereshit - Genesis 22:1) shows that Abraham stood up to his testing.
Test me as you tested Izchak, who being tested on the altar stood up to it. And I, am I without merit?
