וְהַמֶּלֶךְ֮ יִשְׂמַ֪ח בֵּאלֹ֫הִ֥ים יִ֭תְהַלֵּל כָּל־הַנִּשְׁבָּ֣ע בּ֑וֹ כִּ֥י יִ֝סָּכֵ֗ר פִּ֣י דֽוֹבְרֵי־שָֽׁקֶר׃
왕은 하나님을 즐거워하리니 주로 맹세한 자마다 자랑할 것이나 거짓말 하는 자의 입은 막히리로다

ויסכרו, the word is spelled with the letter כ,.which in this instance is used instead of the customary letter ג, in the root סגר. The construction is not unique, as we also find it in Psalms 63,12 כי יסכר פי דובר שקר, “when the mouth of liars is stopped.”
