O Lord, Thou knowest all the snares. Emma Toke, née Leslie. [Lent.] Written in 1851, and contributed anonvmously to the Society for Promoting Christian Knowledge Hymns for Public Worship, 1852, No. 34, in 2 stanzas of 8 lines. From thence it has parsed into later editions of the same collection, the Irish Church Hymnal, and others. In 1870 Mrs. Toke altered it (for the worse) for the Rev. R. Judd's Sunday School Liturgy and Hymn Book, Halifax, 1870, No. 24, as "O God! Thou knowest all the snares," but in this form it has failed to attract attention.
