וַיִּשְׁלַ֞ח מֶ֣לֶךְ יִשְׂרָאֵ֗ל אֶֽל־הַמָּק֞וֹם אֲשֶׁ֨ר אָֽמַר־ל֧וֹ אִישׁ־הָאֱלֹהִ֛ים והזהירה [וְהִזְהִיר֖וֹ] וְנִשְׁמַ֣ר שָׁ֑ם לֹ֥א אַחַ֖ת וְלֹ֥א שְׁתָּֽיִם׃

And the king of Israel sent to the place which the man of God told him and warned him of; and he guarded himself there, not once nor twice.
