Psalms 152 to 155 are additional Psalms found in two Syriac biblical manuscripts and several manuscripts of 's "Book of Discipline", first identified by the orientalist librarian Giuseppe Simone Assemani in 1759. Together with Psalm 151 they are also called the Five Apocryphal Psalms of David or the "Five Syriac Psalms". In addition to Psalm 151, Psalms 154–155 were found in the Dead Sea Scrolls in 11QPs<sup>a</sup>, though 151–155 all were likely composed in Hebrew. This text has survived only in Syriac although the original language may have been Hebrew. The text has six verses, the tone is non-rabbinical, and it was probably composed in Israel during the Hellenistic period (c. 323–31 BC).
Psalm 153
"Spoken by David when returning thanks to God, who had delivered him from the lion and the wolf and he had slain both of them." It is listed as the second of the apocryphal psalms by Wright who calls it "The Prayer of Hezekiah when enemies surrounded him".
Psalm 155
This psalm is extant in Syriac and was also found in the Dead Sea Scroll 11QPs(a)155 (also called 11Q5 – The Great Psalms Scroll), a first-century CE Hebrew manuscript. The psalm has been compared to Psalms 22 and 51 as well as the Prayer of Manasseh.
