אַל־תִּֽירְאוּ֙ בַּהֲמ֣וֹת שָׂדַ֔י כִּ֥י דָשְׁא֖וּ נְא֣וֹת מִדְבָּ֑ר כִּֽי־עֵץ֙ נָשָׂ֣א פִרְי֔וֹ תְּאֵנָ֥ה וָגֶ֖פֶן נָתְנ֥וּ חֵילָֽם׃
Be not afraid, ye beasts of the field; for the pastures of the wilderness do spring, for the tree beareth its fruit, the fig-tree and the vine do yield their strength.
Read halakhic rulings (Jewish law) on Joel 2:22: and classical halakhic sources.
