תהילים ט:ה פירוש: רש״י ורד״ק

my judgment and my cause Heb. משפטי ודיני, words doubled in Scripture, for there is no difference between them, as (in Job 16:19): “my Witness is in heaven, and He Who testifies for me is on high”; (ibid. 40:18), “His limbs are as strong as copper, his bones as a load of iron.”

For Thou hast maintained my right and my cause: – Thou hast fought for me, for it was a great miracle that the stone reached his forehead, as he was altogether clad in iron; and it found an exposed place in his forehead.

my judgment and my cause in heaven (?).
