Reference for Numbers 14:34

בְּמִסְפַּ֨ר הַיָּמִ֜ים אֲשֶׁר־תַּרְתֶּ֣ם אֶת־הָאָרֶץ֮ אַרְבָּעִ֣ים יוֹם֒ י֣וֹם לַשָּׁנָ֞ה י֣וֹם לַשָּׁנָ֗ה תִּשְׂאוּ֙ אֶת־עֲוֺנֹ֣תֵיכֶ֔ם אַרְבָּעִ֖ים שָׁנָ֑ה וִֽידַעְתֶּ֖ם אֶת־תְּנוּאָתִֽי׃

After the number of the days in which ye spied out the land, even forty days, for every day a year, shall ye bear your iniquities, even forty years, and ye shall know My displeasure.
