הַמַּדְלִיק בְּתוֹךְ שְׂדֵה חֲבִרוֹ וְעָבְרָה הַדְּלֵקָה [וְהִזִּיקָה] חַיָּב לְשַׁלֵּם נֵזֶק שָׁלֵם שֶׁנֶּאֱמַר (שמות כב ה) "כִּי תֵצֵא אֵשׁ וּמָצְאָה קֹצִים וְנֶאֱכַל גָּדִישׁ אוֹ הַקָּמָה" וְגוֹ' שַׁלֵּם יְשַׁלֵּם הַמַּבְעִר וְגוֹ'. וְהַבְּעֵרָה מֵאֲבוֹת נְזִיקִין הִיא:
When a person kindles a fire in a field belonging to someone else and the fire spreads and causes damage, [the person who kindled it] is liable to pay the full extent of the damages, as [Exodus 22:5] states: "When a fire spreads through thorns and consumes bound or standing grain..., [the one who started the fire] must pay." Kindling a fire is considered one of the major categories of sources of damage.
