Looking at the HTI, there appear to be three instances, all early 19th c. Scottish - starting with A Selection of Sacred Music, Vol. 4, by James Steven of Glasgow. This is dated to [1801-17] (but possibly is after 1807, as the tune used with this text in Steven's book, Thomas Clark's 'Margate', was published in Clark's A Third Set of Psalm & Hymn Tunes in that year). It doesn't sound like Scottish Psalter, so possibly from early 19th century attempts to introduce hymns or other psalm versions into Scottish use? Being Short Metre, it might be a shortening of something in a longer metre (by omitting words from some lines), but I can't pin down what.
