Halakhah sa 1 Cronica 29:10: Mishneh Torah, The Order, Kitzur Shulchan Arukh, Mishneh Torah, Prayer and the Priestly Blessing & Shulchan Arukh, Orach Chayim

"Blessed is He who spoke, and the world came into being. Blessed is He. Blessed is He who says and does. Blessed is He who decrees and fulfills. Blessed is He who has mercy on the earth. Blessed is He who has mercy on the creatures. Blessed is He who removes darkness and brings light. Blessed is He who rewards those who fear Him. Blessed is He before whom there is no iniquity, no forgetfulness, no falsehood, and no deceit; who shows no favoritism and takes no bribe. Blessed is He, the living God, enduring forever and existing eternally. Blessed are You, Lord our God, King of the universe, the God who is praised by the mouth of His people, lauded and glorified by the tongue of His devout ones and His servants, and by the songs of David, Your servant, Your anointed. We will praise You, Lord our God, with praises and songs. We will thank You, and we will praise You, and we will glorify You, and we will mention Your name, our King, our God, the One who lives forever. Praised and glorified be His great name forever. Blessed are You, Lord, the King who is praised with praises." Then we recite these verses: "May the glory of the Lord endure forever; may the Lord rejoice in His works" (Psalms 104:31), "Ashrei" (Psalms 145), and continue to the end of the Psalms. Afterward, we recite these verses: "Blessed be the Lord forever. Amen and Amen." (Psalms 89:53), "The Lord will reign forever. Amen and Amen." (Psalms 146:10), "And David blessed the Lord before the entire assembly and said: 'Blessed are You, Lord, the God of Israel our father, forever and ever.'" (1 Chronicles 29:10).

You must be careful never to recite a berachah in vain God forbid, or cause yourself to recite a berachah which is unnecessary. If you recited a berachah in vain, or if you uttered the Name of Hashem in vain, you should immediately say: Boruch sheim kevod malchuso le'olam va'ed ["Blessed [is His] Name, Whose glorious kingdom is forever and ever."] If immediately after pronouncing Hashem's Name you remember that the berachah is unnecessary, you should conclude [with]: lamdeini chukecha, (teach me Your laws),¹⁰Psalms 119:12 the complete verse is בָּרוּ אַתָּה ה׳ לַמְדֵנִי חוּקֶךָ. which is a complete verse. Thus it is considered as learning [Torah] and [the Name] was not mentioned in vain. If you began the word Elokeinu [our God], and immediately recall after saying Elokei and have not said the suffix nu you should conclude by saying: Yisrael Aveenu meolam ve'ad olam [Israel our father forever and ever]¹¹The berachah is now a Scriptural verse which reads Blessed are you God, God of Israel, our Father, forever and ever. (which is also the syntax of a verse in Chronicles I, Chapter 29). Nevertheless you should also say: Boruch sheim kevod malchuso le'olam va'ed (See Tzlach, Maseches Berachos, Page 39).

The early Sages lauded one who reads every day psalms from the Psalter, beginning with "the Psalm of David" (Psalm 145) and continuing till the end of the book. It is also settled practice to read verses before and after these Psalms. The Sages appointed a blessing to be recited before the psalms, the one beginning, "Blessed be He who spake", and a blessing to be recited after them, beginning, "Praised be Thy name." Then the blessings for the Shema are recited and the Shema is read.
