Sirach does not mention the names of Adam and Moses in this passage, but he is clearly recalling the history of Salvation from Adam to Moses. He speaks first of all of the creation of humanity from the earth. Towards the end of the passage he speaks about covenant, commandment and portion: all referring to the experience of Israel in the desert under the leadership of Moses. By not mentioning the names of the two men, Adam and Moses, the author possibly desires us to give all our attention to what God is doing. Indeed, almost every verse begins with a reference to God. It is God's activity in human history which makes it a history of grace, a history blessed by grace.

The psalm recalls for us a special aspect of God's grace - namely God's compassion. To enjoy this compassion of God we must be counted among those "who keep his covenant". We may not always keep the covenant by living perfect lives - indeed, the psalmist reminds us that we are made of dust, and therefore weak. It is a consolation for us that the Lord "knows how we are formed" and so desires to manifest the fullness of saving mercy and compassion.
