לָכֵן֩ יִֽהְיֶ֨ה דַרְכָּ֜ם לָהֶ֗ם כַּחֲלַקְלַקּוֹת֙ בָּֽאֲפֵלָ֔ה יִדַּ֖חוּ וְנָ֣פְלוּ בָ֑הּ כִּֽי־אָבִ֨יא עֲלֵיהֶ֥ם רָעָ֛ה שְׁנַ֥ת פְּקֻדָּתָ֖ם נְאֻם־יְהוָֽה׃
Wherefore their way shall be unto them as slippery places in the darkness, They shall be thrust, and fall therein; For I will bring evil upon them, Even the year of their visitation, Saith the LORD.
