א֠וֹ מִכֹּ֞ל אֲשֶׁר־יִשָּׁבַ֣ע עָלָיו֮ לַשֶּׁקֶר֒ וְשִׁלַּ֤ם אֹתוֹ֙ בְּרֹאשׁ֔וֹ וַחֲמִשִׁתָ֖יו יֹסֵ֣ף עָלָ֑יו לַאֲשֶׁ֨ר ה֥וּא ל֛וֹ יִתְּנֶ֖נּוּ בְּי֥וֹם אַשְׁמָתֽוֹ׃

or any thing about which he hath sworn falsely, he shall even restore it in full, and shall add the fifth part more thereto; unto him to whom it appertaineth shall he give it, in the day of his being guilty.
