If ye then being evil know how to give good gifts unto
your children (See Gill on Matthew 7:11).
How much more shall your heavenly Father give the Holy Spirit to
them that ask him?
instead of the Holy Spirit here, the Vulgate Latin version reads, "good Spirit", and so two copies of Beza's; and the Ethiopic version, "the good gift of the Holy Spirit"; and doubtless intends the gifts and graces of the Holy Spirit, in distinction from, and as preferable to the good things given by earthly parents, to their children.
