Passage
He answered: I will shew thee all good, and I will proclaim in the name of the Lord before thee: and I will have mercy on whom I will, and I will be merciful to whom it shall please me.
He answered: I will shew thee all good, and I will proclaim in the name of the Lord before thee: and I will have mercy on whom I will, and I will be merciful to whom it shall please me.
Exodus 33:17 And the Lord said to Moses: This word also, which thou hast spoken, will I do; for thou hast found grace before me, and thee I have known by name.
Exodus 33:18 And he said: Shew me thy glory.
Exodus 33:19 He answered: I will shew thee all good, and I will proclaim in the name of the Lord before thee: and I will have mercy on whom I will, and I will be merciful to whom it shall please me.
Exodus 33:20 And again he said: Thou canst not see my face: for man shall not see me, and live.
Exodus 33:21 And again he said: Behold there is a place with me, and thou shalt stand upon the rock.
The verse centers on "mercy", "answered", "shew", "thee", "good", "proclaim", "name", and "lord". It is saying that the verse draws attention to "mercy" and "answered", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "And he said Shew me thy glory..." into verse 20's "And again he said Thou canst not...", so "mercy" and "answered" belong inside that flow. In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "answered" with trust shaped by these words, not by a vague optimism outside the passage.
