Proverbs 17:17 He that is a friend loveth at all times: and a brother is proved in distress.
The verse centers on "condemn", "justifieth", "wicked", "condemneth", "both", "abominable", and "before". It is saying that the verse draws attention to "condemn" and "justifieth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "The beginning of quarrels is as when..." into verse 16's "What doth it avail a fool to...", so "condemn" and "justifieth" belong inside that flow. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "condemn" and "justifieth" with trust shaped by these words, not by a vague optimism outside the passage.
