Now for a recompence in the same, (I speak as unto my children,) be ye also enlarged.
'For (as) a recompence of the same kind ... be enlarged also yourselves.' 'In the same way' as my heart is enlarged toward you (2 Corinthians 6:11), and as "a recompence" for it (Galatians 4:12), I ask love for love.
(I speak as unto my children) - as children would naturally recompense their parents' love with similar love.
