וַיֹּאמֶר ה' אֶל־מֹשֶׁה עַד־אָנָה יְנַאֲצֻנִי הָעָם הַזֶּה
וְעַד־אָנָה לֹא־יַאֲמִינוּ בִי בְּכֹל הָאֹתוֹת אֲשֶׁר עָשִׂיתִי בְּקִרְבּוֹ׃
And the LORD said to Moses, “How long will this people spurn Me, and how long will they have no faith in Me despite all the signs that I have performed in their midst? (Num 14,11)
This pattern of G-d complaining about His patience expiring is very common in the Torah. Moreover, it appears that people suffer harder punishment from G-d when sinning for another time. This appears contradicting the idea of "מלך בשר ודם" vs "מלך מה"מ" - G-d being ultimately just, and contradicting our current state of Halacha.
G-d does not have (shouldn't have) tolerance or patience, not mentioning it to expire, IMHO.
Does G-d have an expiration on His tolerance? (and if yes,) Why does Torah picture G-d as such?
