Brachot 9b as translated by Soncino
Seeing that this verse, ‘Let the words of my mouth be acceptable etc.’ is suitable for recital either
at the end or the beginning [of the tefillah], why did the Rabbis institute it at the end of the eighteen
benedictions? Let it be recited at the beginning? — R. Judah the son of R. Simeon b. Pazzi said:
Since David said it only after eighteen chapters [of the Psalms],31 the Rabbis too enacted that it
should be said after eighteen blessings. But those eighteen Psalms are really nineteen? — ‘Happy is
the man’ and ‘Why are the nations in an uproar’32 form one chapter. For R. Judah the son of R.
Simeon b. Pazzi said: David composed a hundred and three chapters [of psalms], and he did not say
‘Hallelujah’ until he saw the downfall of the wicked, as it says, Let sinners cease out of the earth,
and let the wicked be no more. Bless the Lord, O my soul. Hallelujah.33 Now are these a hundred
and three? Are they not a hundred and four? You must assume therefore that ‘Happy is the man’ and
‘Why are the nations in an uproar’ form one chapter. For R. Samuel b. Nahmani said in the name of
R. Johanan: Every chapter that was particularly dear to David he commenced with ‘Happy’ and terminated with
‘Happy’.1 He began with ‘Happy’, as it is written, ‘Happy is the man’, and he terminated with
‘Happy’, as it is written, ‘happy are all they that take refuge in Him’.2
