Now therfore shall ye not giue your daughters vnto their sonnes, neither shall ye take their daughters vnto your sonnes, nor seeke their peace nor wealth for euer, that yee may be strong and eate the goodnes of the lande, and leaue it for an inheritance to your sonnes for euer.
Ezra 9:10 And nowe, our God, what shall we say after this? for we haue forsaken thy commandements,
Ezra 9:11 Which thou hast commanded by thy seruants the Prophets, saying, The land whereunto ye go to possesse it, is an vncleane land, because of the filthines of the people of the lands, which by their abominations, and by their vncleannes haue filled it from corner to corner.
Ezra 9:12 Now therfore shall ye not giue your daughters vnto their sonnes, neither shall ye take their daughters vnto your sonnes, nor seeke their peace nor wealth for euer, that yee may be strong and eate the goodnes of the lande, and leaue it for an inheritance to your sonnes for euer.
Ezra 9:13 And after all that is come vpon vs for our euill deedes, and for our great trespasses, (seeing that thou our God hast stayed vs from being beneath for our iniquities, and hast giuen vs such deliuerance)
Ezra 9:14 Should we returne to breake thy commadements, and ioyne in affinitie with the people of such abominations? wouldest not thou be angrie towarde vs till thou haddest consumed vs, so that there should be no remnant nor any escaping?
The verse centers on "therfore", "shall", "giue", "daughters", "vnto", "sonnes", and "neither". It is saying that the verse draws attention to "therfore" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "Which thou hast commanded by thy seruants..." into verse 13's "And after all that is come vpon...", so "therfore" and "shall" belong inside that flow. In Ezra context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "therfore" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
