עַתָּ֡ה הִנֵּ֣ה בָטַ֣חְתָּ לְּךָ֡ עַל־מִשְׁעֶנֶת֩ הַקָּנֶ֨ה הָרָצ֤וּץ הַזֶּה֙ עַל־מִצְרַ֔יִם אֲשֶׁ֨ר יִסָּמֵ֥ךְ אִישׁ֙ עָלָ֔יו וּבָ֥א בְכַפּ֖וֹ וּנְקָבָ֑הּ כֵּ֚ן פַּרְעֹ֣ה מֶֽלֶךְ־מִצְרַ֔יִם לְכָֽל־הַבֹּטְחִ֖ים עָלָֽיו׃
看哪，如今你所倚仗的，是埃及這根壓傷的蘆葦杖；人若靠著它，它就必刺進他的手掌，把手刺透。埃及王法老對一切倚仗他的人，也是這樣。
Rashi
It will go into his palm. When a person supports himself on a support of a splintered reed, which has broken in his hand, the splintered edges come and puncture his palm.14Similarly, his reliance on Paroh for support will turn out to be bad for him.
