Reference for Leviticus 19:23

וְכִי־תָבֹ֣אוּ אֶל־הָאָ֗רֶץ וּנְטַעְתֶּם֙ כָּל־עֵ֣ץ מַאֲכָ֔ל וַעֲרַלְתֶּ֥ם עָרְלָת֖וֹ אֶת־פִּרְי֑וֹ שָׁלֹ֣שׁ שָׁנִ֗ים יִהְיֶ֥ה לָכֶ֛ם עֲרֵלִ֖ים לֹ֥א יֵאָכֵֽל׃

And when ye shall come into the land, and shall have planted all manner of trees for food, then ye shall count the fruit thereof as forbidden; three years shall it be as forbidden unto you; it shall not be eaten.
