Analysis of information sources in references of the Wikipedia article "Psalms 152–155" in English language version.
The original language of this psalm, which is extant only in Syriac, may be Hebrew... It is impossible to date this psalm. The general tone, Jewish but non-rabbinic character, and association with Psalms 151, 154 and 155 indicate that it was probably composed by a Palestinian Jew during the hellenistic period.
Prior to their discovery at Qumran, the additional psalms of David survived primarily through Syriac copies, and scholars referred to them as Syria noncanonical psalms. Of these psalms, Psalms 151A, 151B and 155 are present within the Qumran Psalms Scroll (11QPsa), and are thus clearly pre-Christian in their composition.
