Yeshayah 36:6

6 Hinei, thou trustest in the mishenet (staff) of this broken reed, on Mitzrayim; whereon if an ish lean, it will go into his palm, and pierce it; so is Pharaoh Melech Mitzrayim to all that trust in him.

Yeshayah 36:6 Meaning and Commentary

Isaiah 36:6

Lo, thou trustest in the staff of this broken reed, on Egypt,
&c.] His ally and auxiliary; and which is rightly called "the staff of a broken reed", if trusted to, and leaned upon, being weak and frail, and an insufficient ground of confidence to depend upon; the allusion seems to be to the cane or reed which grew upon the banks of the river Nile, in Egypt: whereon if a man lean, it will go into his hand, and pierce it;
the splinters of the broken reed being leaned on, will enter into a man's hand, and do him harm, instead of being a help to him to walk with: so is Pharaoh king of Egypt to all that trust in him;
pernicious and harmful, instead of being useful and helpful.

Yeshayah 36:6 In-Context

4 And Rav Shakeh said unto them, Say ye now to Chizkiyah, Thus saith the HaMelech Hagadol, Melech Ashur, What bitachon (confidence) is this wherein thou trustest?

5 I say, Your etzah (counsel) and gevurah (strength) for milchamah (war) are only devar sefatayim [words of the lips, empty words]); now on whom dost thou trust, that thou rebellest against me?

6 Hinei, thou trustest in the mishenet (staff) of this broken reed, on Mitzrayim; whereon if an ish lean, it will go into his palm, and pierce it; so is Pharaoh Melech Mitzrayim to all that trust in him.

7 But if thou say to me, We trust in Hashem Eloheinu; is it not He, whose high places and whose mizbechot Chizkiyah hath taken away, and said to Yehudah and to Yerushalayim, Ye shall worship before this Mizbe’ach?

8 Therefore give pledges, now, to adoni HaMelech Ashur, and I will give thee two thousand susim, if thou be able on thy part to set riders upon them.
