'Day of Salvation' in the Bible

This is what the Lord says,“In a favorable time I have answered You,And in a day of salvation I have helped You;And I will keep watch over You and give You for a covenant of the people,To restore the land [from its present state of ruin] and to apportion and give as inheritances the deserted hereditary lands,

For He says,“At the acceptable time (the time of grace) I listened to you,And I helped you on the day of salvation.” Behold, now is “the acceptable time,” behold, now is “the day of salvation”—
