Komentaryong Sumisipi para sa Mga Awit 91:8

הלא הוא כמוס עמדי, “have I not carefully stored it away?” Their wine is stored away under My care until they will drink it. Sooner or later they themselves will have to drink their own poisonous wine. G’d is storing up His eventual vengeance against the people who have abused Israel. The construction is similar to Psalms 91,8: “you will witness the punishment of the wicked with your eyes.” [A reference to the words in verse 35 לי נקם ושלם, i.e. verses 34 and 35 are one unit. Ed.] לעת תמוט רגלם “at the time when their foot shall slip.” When the measure of their sins is full. The word שלם here is used by Moses in the same vein as G’d used it when explaining to Avraham in Genesis 15,16 that the Emorite people could not be driven out of the land of Canaan until its measure of guilt was full, שלם.
