Kidushin 30b: Since it says also "Kabed Es Avicha v'Es Imecha" (Shemos 20:12), this teaches that honor of parents is equated to Hashem's honor.

Rashi: Honor him from everything that Chanancha (He graced you), even a pleasant voice. (Some texts - we read me'Honecha like me'Geronecha.)

R. Yonah (9-10, 26): This returns to Bitachon. Do not be stingy about spending money for Mitzvos and Tzedakos. Do not fear lest your wealth lack via giving. Rather, trust in Hashem, for due to this He will bless you, and everything of yours will increase, like it will explain. Hon includes everything that people store in storehouses, like "Lo Amru Hon" (30:15). Mesiras Nefesh is the second level of Bitachon. He trusts in Hashem to choose for him the good path - "Hodi'eni Na Es Derachecha" (Shemos 33:13). He knows that everything that Shamayim does is for good (Brachos 60b). He accepts all that comes on him with love, and knows that it is his good and Kaparah for his sins, more than what he requests! He does not know what is good for his Nefesh - "Gam Es ha'Tov Nekabel me'Es ha'Elokim" (Iyov 2:10). If there is wealth in his house, all that he benefits from it, he considers it a gift. Nothing is from his wealth or ability - "umi'Yadecha Nasanu Lach" (Divrei ha'Yamim I, 29:14). It says about one who serves from love and happily accepts afflictions "v'Ohavav k'Tzeis ha'Shemesh bi'Gvuraso" (Shoftim 5:31) (Shabbos 88b).

Malbim: After teaching to know Hashem in all his ways, for the laws of Chachmah will be a cure for him, it adds that from all that you acquire and your grain, attribute the first to Hashem, for He gives everything; everything is from His hand.

Rashi: These are Terumos and Ma'aseros.

Malbim: This is a Mashal for Chachmah, which is the absolute beginning of all actions. Targum Yerushalmi of "Bereishis" is b'Chuchma. You must return it to Hashem, and know that all its Chukim are from Him. Do not be Chacham b'Einecha to attribute Chachmah to your Binah.
