וְהָי֤וּ כְגִבּוֹר֙ אֶפְרַ֔יִם וְשָׂמַ֥ח לִבָּ֖ם כְּמוֹ־יָ֑יִן וּבְנֵיהֶם֙ יִרְא֣וּ וְשָׂמֵ֔חוּ יָגֵ֥ל לִבָּ֖ם בַּיהוָֽה׃
And they of Ephraim shall be like a mighty man, And their heart shall rejoice as through wine; Yea, their children shall see it, And rejoice, their heart shall be glad in the LORD.
