כִּֽי־עָ֭שִׂיתָ מִשְׁפָּטִ֣י וְדִינִ֑י יָשַׁ֥בְתָּ לְ֝כִסֵּ֗א שׁוֹפֵ֥ט צֶֽדֶק׃
Sebab Engkau telah membela hakku dan perkaraku; Engkau duduk di atas takhta sebagai Hakim yang adil.

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.
