1. "To call unto me (God)" is to cry to God for help and succor, to seek safety and deliverance with him. It is not the same with that other expression, viz. "to call on the Name of Jehovah," which is rather to reverence and worship Jehovah.
2. The word דין is more poetic than שָׁפַט, though the meaning of both is "judging," the latter probably derived from שָׁפַח, to set, then to set right, defend.
3. Their not calling unto God is well explained by Kimchi as follows: "Also they (the people) had failed by the hand of their enemies, the kings of the Gentiles; but, notwithstanding this, no one among them calls to me. They should have thought in their heart, There is no power in the hand of our king to help us out of our distress; we will turn to Jehovah, for he will be our Helper." This verse is not so difficult as the three preceding; we proceed, therefore, in regular order to the next.
