Answer:
The second sentence (And I hereby enjoin upon the people so declared to be free to abstain from all violence, unless in necessary self-defense; and I recommend to them that, in all case when allowed, they labor faithfully for reasonable wages.
.)
Step-by-step explanation:
This sentence, specifically pointing at the phrase "abstain from all violence..." and "they labor faithfully for reasonable wages" implies that Lincoln does not wish to infringe on the rights of former slaves but wishes to clarify that he does not condone violence against former masters but supports freedman work as long as it is with "reasonable wages"
I hope that this helps you!!!
