Heres 2 Pesukim from Tanach:
Torah discusses the consequences that will befall the Jewish People if they do not adhere to the Torah. It is said (Devarim 28:47) tachas asher lo avadata es HaShem Elokecha bisimcha uvituv leivav meirov kol, because you did not serve HaShem, your G-d, amid gladness and goodness of heart, when everything was abundant.
Ivdu es Hashem b’simcha’ (serve Hashem with
joy) of Tehillim (Psalms) 100:2
