49 Remember the word to Your servant,
In which You have made me hope.
50 This is my comfort in my misery,
That Your word has revived me.
51 The arrogant utterly deride me,
Yet I do not turn aside from Your Law.
52 I have remembered Your judgments from of old, Lord,
And comfort myself.
53 Burning indignation has seized me because of the wicked,
Who abandon Your Law.
54 Your statutes are my songs
In the house of my pilgrimage.
55 Lord, I remember Your name in the night,
And keep Your Law.
56 This has become mine,
That I comply with Your precepts.
In His Service,
Minister A. Francine Green
