Yet if they turne againe vnto their heart in the lande (to the which they be caryed away captiues) and returne and pray vnto thee in the lande of them that caryed them away captiues, saying, We haue sinned, we haue transgressed, and done wickedly,
1 Kings 8:45 Heare thou then in heauen their prayer and their supplication, and iudge their cause.
1 Kings 8:46 If they sinne against thee, ( for there is no man that sinneth not) and thou be angry with them, and deliuer them vnto the enemies, so that they cary them away prisoners vnto the land of the enemies, either farre or neere,
1 Kings 8:47 Yet if they turne againe vnto their heart in the lande (to the which they be caryed away captiues) and returne and pray vnto thee in the lande of them that caryed them away captiues, saying, We haue sinned, we haue transgressed, and done wickedly,
1 Kings 8:48 If they turne againe vnto thee with all their heart, and with all their soule in the lande of their enemies, which led them away captiues, and pray vnto thee toward the way of their land, which thou gauest vnto their fathers, and toward the citie which thou hast chosen, and the house, which I haue built for thy Name,
1 Kings 8:49 Then heare thou their prayer and their supplication in heauen thy dwelling place, and iudge their cause,
The verse centers on "turne", "againe", "vnto", "heart", "lande", "caryed", "away", and "captiues". It is saying that the verse draws attention to "turne" and "againe", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 46's "If they sinne against thee for there..." into verse 48's "If they turne againe vnto thee with...", so "turne" and "againe" belong inside that flow. In 1 Kings context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "turne" and "againe" with trust shaped by these words, not by a vague optimism outside the passage.
