Book of Psalms in Smiths Bible Dictionary
            The present Hebrew name of the book is Tehill'im, 
"Praises;" but in the actual superscriptions of the psalms 
the word Tehillah is applied only to one, Ps 145:1 ... which 
is indeed emphatically a praise-hymn. The LXX. entitled them 
psalmoi or "psalms," i.e., lyrical pieces to be sung to a 
musical instrument. The Christian Church obviously received 
the Psalter from the Jews not only as a constituent portion 
of the sacred volume of Holy Scripture, but also as the 
liturgical hymn-book which the Jewish Church had regularly 
used in the temple. Division of the Psalms. --The book 
contains 150 psalms, and may be divided into five great 
divisions or books, which must have been originally formed 
at different periods. Book I. is, by the superscriptions, 
entirely Davidic nor do we find in it a trace of any but 
David's authorship. We may well believe that the compilation 
of the book was also David's work. Book II. appears by the 
date of its latest psalm, Ps 46:1 ... to have been compiled 
in the reign of King Hezekiah. It would naturally comprise, 
1st, several or most of the Levitical psalms anterior to 
that date; and 2d, the remainder of the psalms of David 
previously uncompiled. To these latter the collector after 
properly appending the single psalm of Solomon has affixed 
the notice that "the prayers of David the son of Jesse are 
ended." Ps 72:20 Book III., the interest of which centers in 
the times of Hezekiah stretches out, by its last two psalms, 
to the reign of Manasseh: it was probably compiled in the 
reign of Josiah. It contains seventeen psalms, from Psal 73-
89 eleven by Asaph, four by the sons of Horah, one (86) by 
David, and one by Ethan. Book IV. contains the remainder of 
the psalms up to the date of the captivity, There are 
seventeen, from Psal 90-106 --one by Moses, two by David, 
and the rest anonymous. Book V., the psalms of the return, 
contains forty-four, from Psal 107-180 --fifteen by David, 
one by Solomon and the rest anonymous. There is nothing to 
distinguish these two books from each other in respect of 
outward decoration or arrangement and they may have been 
compiled together in the days of Nehemiah. Connection of the 
Psalms with Israelitish history. --The psalm of Moses Psal 
90, which is in point of actual date the earliest, 
faithfully reflects the long, weary wanderings, the 
multiplied provocations and the consequent punishments of 
the wilderness. It is, however, with David that Israelitish 
psalmody may be said virtually to commence. Previous mastery 
over his harp had probably already prepared the way for his 
future strains, when the anointing oil of Samuel descended 
upon him, and he began to drink in special measure, from 
that day forward, of the Spirit of the Lord. It was then 
that, victorious at home over the mysterious melancholy of 
Saul and in the held over the vaunting champion of the 
Philistine hosts, he sang how from even babes and sucklings 
God had ordained strength because of his enemies. Psal 8. 
His next psalms are of a different character; his 
persecutions at the hands of Saul had commenced. When 
David's reign has begun, it is still with the most exciting 
incidents of his history, private or public, that his psalms 
are mainly associated...
