לֹ֣א תְנַסּ֔וּ אֶת־יְהוָ֖ה אֱלֹהֵיכֶ֑ם כַּאֲשֶׁ֥ר נִסִּיתֶ֖ם בַּמַּסָּֽה׃
Não tentarão a Yehová, seu Elohim, como o tentaram em Massá.
Sefer HaMitzvot
That He prohibited us - not to test [His] assurances and threats of which His prophets have assured us - in the way of a doubt that we doubt them - once we have ascertained the truth of the prophet that is saying them. And that is His, may He be exalted, saying, "You shalt not test the Lord, your God" (Deuteronomy 6:16). (See Parashat Vaetchanan; Mishneh Torah, Foundations of the Torah at the end.)
