כִּֽי־יִבְעַ֤ל בָּחוּר֙ בְּתוּלָ֔ה יִבְעָל֖וּךְ בָּנָ֑יִךְ וּמְשׂ֤וֹשׂ חָתָן֙ עַל־כַּלָּ֔ה יָשִׂ֥ישׂ עָלַ֖יִךְ אֱלֹהָֽיִךְ׃
Sapagkat kung paanong pinakakasalan ng isang binata ang isang dalaga, gayon ka pananahanan ng iyong mga anak; at kung paanong nagagalak ang lalaking ikakasal sa kanyang nobya, gayon magagalak sa iyo ang iyong Diyos.
Rashi
As a young man lives with a virgin, etc. As a young man lives with a virgin, so shall your children live in you [after Jonathan].
Ibn Ezra
So shall thy sons marry thee. This is a figurative expression for the kingdom will be restored to thee.
Tze'enah Ure'enah
“As a youth espouses a maiden, etc.” [62:5]. Just as when a youth espouses a maiden, this is a much more appropriate match than if an old man takes a maiden. So too was the land of Israel. Because Israel was in exile, when the nations lived in it, it was like an old man espousing a maiden. However, when Israel will again come to the land of Israel it will be like a youth espousing a maiden. Just as a groom rejoices with his bride, so will the Holy One rejoice with you.4Radak, Isaiah, 62:5.
