   In Matthew 10:25, the neuter nominative singular form occurs in the statement that it is enough for a disciple to become like the teacher and a slave like the lord. In Matthew 6:34, the same form stands with the day's own trouble; in 1 Peter 4:3, the masculine nominative singular form describes the time that has passed in relation to the Gentiles' plan.

In the Anselm Project Bible: The APB presents the clause with “enough” in Matthew 10:25 and with “Sufficient” in Matthew 6:34 and 1 Peter 4:3. These renderings confirm the clauses' overall presentation rather than isolate the term in every detail.
