Sirach 43:29–31

29 The Lord is terrible and very great, and marvellous is his power. 30 When ye glorify the Lord, exalt him as much as ye can; for even yet will he far exceed: and when ye exalt him, put forth all your strength, and be not weary; for ye can never go far enough. 31 Who hath seen him, that he might tell us? and who can magnify him as he is?
