治ちに居いて乱らんを忘わすれず

expression

forewarned is forearmed; in fair weather prepare for foul; don't forget war in time of peace

Proverb advising preparedness and vigilance even in peaceful times. Literally: 'While in peace, do not forget war.'

• 「治ちに居いて乱らんを忘わすれず」という言こと葉ばを胸むねに刻きざんで、日ひ々びの備そなえを怠おこたらないようにしている。

  I keep the saying 'forewarned is forearmed' in mind and try not to neglect daily preparations.
