Now, my son, the Lord be with thee
 Or "shall be with thee" F18, as some; and if it be as a prayer, it was no doubt a prayer of faith; the Targum is, 
``may the Word of the Lord be thine help:''and prosper thee;
 and build the house of the Lord thy God, as he hath said of thee;
 foretold he should, and therefore would assist him to do it, which was an encouragement to go about it.
