2 Samuel 12:21 Then saide his seruants vnto him, What thing is this, that thou hast done? thou diddest fast and weepe for the childe while it was aliue, but when the childe was dead, thou diddest rise vp, and eate meate.

The verse centers on "mercy", "sayde", "childe", "aliue", "fasted", "wept", "tell", and "whether". It is saying that the verse draws attention to "mercy" and "sayde", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "Then saide his seruants vnto him What..." into verse 23's "But now being dead wherefore shoulde I...", so "mercy" and "sayde" belong inside that flow. In 2 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "sayde" with trust shaped by these words, not by a vague optimism outside the passage.
