Say, "'_Love your enemies_,' is a divine command."
Or, "_We are divinely commanded to love_ our enemies." Some are apt to
jumble together the active voice and the passive, and thus destroy the
unity even of a short sentence; as, "By _exercising_ our memories, they
_are improved_."--_Kirkham's Gram._, p. 226 and 195. "The error _might have
been avoided_ by _repeating_ the substantive."--_Murray's Gram._, p. 172.
"By _admitting_ such violations of established grammatical distinctions,
confusion _would be introduced_."--_Ib._, p. 187. In these instances, we
have an active participle without an agent; and this, by the preposition
_by_, is made an adjunct to a passive verb. Even the participial noun of
this form, though it actually drops the distinction of voice, is awkward
and apparently incongruous in such a relation.

OBS. 11.--When the verbal noun necessarily retains any adjunct of the verb
or participle, it seems proper that the two words be made a compound by
means of the hyphen: as, "Their hope shall be as the _giving-up_ of the
ghost."--_Job_, xi, 20. "For if the _casting-away_ of them be the
reconciling of the world."--_Rom._, xi, 15. "And the _gathering-together_
of the waters called he seas."--_Gen._, i, 10. "If he should offer to stop
the _runnings-out_ of his justice."--_Law and Grace_, p. 26. "The
_stopping-short_ before the usual pause in the melody, aids the impression
that is made by the description of the stone's _stopping-short_.'"--_Kames,
El. of Crit._, ii, 106. I do not find these words united in the places
referred to, but this is nevertheless their true figure. Our authors and
printers are lamentably careless, as well as ignorant, respecting _the
figure of words_: for which part of grammar, see the whole of the third
chapter, in Part First of this work; also observations on the fourth rule
of syntax, from the 30th to the 35th. As certain other compounds may
sometimes be broken by _tmesis_, so may some of these; as, "Not forsaking
the _assembling_ of ourselves _together_, as the manner of some
is."--_Heb._, x, 23. Adverbs may relate to participles, but nouns require
adjectives. The following phrase is therefore inaccurate: "For the more
_easily_ reading of large numbers." Yet if we say, "For reading large
numbers _the more easily_," the construction is different, and not
inaccurate. Some calculator, I think, has it, "For the more _easily_
reading large numbers." But Hutton says, "For the more _easy_ read
