Tehillim
בראשית מז,כט: וַיִּקְרְבּוּ יְמֵי־יִשְׂרָאֵל לָמוּת
The Baal HaTurim writes that the phrase ויקרבו ימי also occurs by the death of Dovid haMelech. The Medrash states that HaShem told Dovid to compose 147 kepital corresponding to the years of the life of Yaacov. You should also merit that your son also reign during your lifetime.
Yaacov is connected to Tehillim that during the years that he worked by Lavan he would not lie down at night (since he was hired to watch the flocks). Therefore, he stays awake and recited the entire Tehillim.
Although the chapters divisions of the other books of Tanach are not of a Jewish origin, the common division of Sefer Tehillim is ancient. The usual count is 150, but some sources have a few chapters joined as one, which result in the total of 147.

Chesed shel Emes
בראשית מז, כט: וְעָשִׂיתָ עִמָּדִי חֶסֶד וֶאֱמֶת
As Rashi explains that truth defines the type of kindness, which is one performed for the dead (from whom one would not expect repayment). The Baal haTurim observes the word אמת is an acronym for the following: ארון (coffin), מטה (bier), תכריכין (shrouds).
12 Tribes
בראשית מח,ה: אֶפְרַיִם וּמְנַשֶּׁה כִּרְאוּבֵן וְשִׁמְעוֹן יִהְיוּ־לִי
The Baal HaTurim observes that the phrase אפרים ומנשה have the same Gematria value (732) as the phrase ראובן ושמעון. That is why Yaacov said that they would receive an equal portion to them.
'And if you will ask', said Yaacov, 'how I can possibly place my grandchildren on a par with my children?' Yaacov says the answer is that when, 'after I left Padan Aram, G-d said to me that I should be fruitful and multiply, that a nation and an assembly of nations will descend from me, I understood this to mean that I will still bear children from Rochel. But Rochel died. So now it is from you (Yosef) from whom these "children" will descend!'
Devorah
בראשית מח, כא: נַפְתָּלִי אַיָּלָה שְׁלֻחָה
The Baal haTurim explains that this refers to the battle between Sisra, king of Canaan, and Barak captain of the army of Yisrael, who picked ten thousand men from Naftali. And the Torah refers here to a female deer due to the major role played in that battle by the prophetess Devorah (Barak's wife).
"ha'nosein imrei shefer", he continues, refers to the beautiful song of praise that she subsequently sang (Shiras Devorah). "Imrei shefer", he points out, has the same Gematriya as 'shir u'shevochah', and "... ayalah sheluchah, ha'nosein imrei shefer" as the Pasuk "Va'toshar Devorah u'Barak ben Avino'am ba'yom ha'hu" (the introductory words of the Shiras Devorah).
