Look closely at the words

01The eternal Creator stands aloneThe passage begins with the Lord’s uniqueness. He lives forever and created the whole universe.
Explanation
The passage begins with the Lord’s uniqueness. He lives forever and created the whole universe. It also says, “The Lord alone is just.” These opening lines place God above everything else. His life does not end, and his justice is not shared out as though he were only one power among many.
02God’s works and mercy are beyond full human measuringSirach asks who could trace God’s mighty deeds, measure the strength of his majesty, or fully proclaim his mercies.
Explanation
Sirach asks who could trace God’s mighty deeds, measure the strength of his majesty, or fully proclaim his mercies. It says no one has been given power to declare all his works. Nothing can be added to or taken from his wondrous works, and they cannot be fully explored.
03Human understanding reaches its limits quicklyAfter describing the Lord’s greatness, the passage turns to people. Even when someone thinks the work is finished, it is only a beginning, and stopping brings perplexity.
Explanation
After describing the Lord’s greatness, the passage turns to people. Even when someone thinks the work is finished, it is only a beginning, and stopping brings perplexity. Then come searching questions about mankind, their purpose, and their good and evil. Human knowledge and human life are both shown to be limited.
04Brief lives meet patient mercyA human life is described as, at most, a hundred years, but those years are like a drop from the sea or a pebble from the sand compared with eternity.
Explanation
A human life is described as, at most, a hundred years, but those years are like a drop from the sea or a pebble from the sand compared with eternity. For that reason, the Lord is patient and pours out mercy. He sees the human end is evil, so he multiplies forgiveness.
05The Lord’s mercy includes correction and returnHuman mercy reaches to a neighbour, but the Lord’s mercy is said to be on all flesh. That mercy includes reproving, chastening, teaching and bringing back, like a shepherd with a flock.
Explanation
Human mercy reaches to a neighbour, but the Lord’s mercy is said to be on all flesh. That mercy includes reproving, chastening, teaching and bringing back, like a shepherd with a flock. The passage ends by saying he has mercy on those who accept chastening and diligently seek his judgments.

Sirach 18:1–2
1He who lives forever created the whole universe.
2The Lord alone is just.
Sirach 18:4–14
4He has given power to declare his works to no one. Who could trace out his mighty deeds?
5Who could measure the strength of his majesty? Who could also proclaim his mercies?
6As for the wondrous works of the Lord, it is not possible to take from them nor add to them, neither is it possible to explore them.
7When a man has finished, then he is just at the beginning. When he stops, then he will be perplexed.
8What is mankind, and what purpose do they serve? What is their good, and what is their evil?
9The number of man’s days at the most are a hundred years.
10As a drop of water from the sea, and a pebble from the sand, so are a few years in the day of eternity.
11For this cause the Lord was patient over them, and poured out his mercy upon them.
12He saw and perceived their end, that it is evil. Therefore he multiplied his forgiveness.
13The mercy of a man is on his neighbor; but the mercy of the Lord is on all flesh: reproving, chastening, teaching, and bringing back, as a shepherd does his flock.
14He has mercy on those who accept chastening, and that diligently seek after his judgments.
