Troparion of Saint Nicolas in Tone 4
Truth has revealed you to your flock as a rule of faith,
a model of meekness, and a teacher of abstinence.
Therefore you have won the heights by humility,
riches by your poverty.
Holy Father Nicholas, our great High Priest
intercede with Christ our God that our souls may be saved.
