Athanasius of Alexandria : At no time should one freely praise God more than when one has passed through afflictions. Nor again should one at any time give thanks more than when he finds rest from toil and temptations. As Hezekiah, when the Assyrians perished, praised the Lord and gave thanks, saying, "The Lord is my salvation, and I will not cease to bless you with harp all the days of my life, before the house of the Lord." — Letter 10.3 Jerome : (Verse 20) Lord, save me, and we will sing our songs all the days of our life in the house of the Lord. Therefore save me, O Lord; and all who believe in you and are delivered by your help, may we sing to you in the Temple all the days of our life. — Commentary on Isaiah
