Numbers 33:55 Meaning and Commentary

Numbers 33:55

But if ye will not drive out the inhabitants of the land
before you
Should be remiss and careless about it, and indifferent to it, and not make use of the proper means to get rid of them, but, on the contrary, make covenants with them, and intermarry among them; or, however, become friendly to them, and suffer them to dwell among them:

then it shall come to pass, that those which ye let remain of them;
sparing their lives, and permitting them to dwell among them:

shall be pricks in your eyes, and thorns in your sides;
which figurative expressions show that they should be very troublesome and distressing to them, even in their most tender and nearest concerns, and dearest relations, and which are explained and more properly expressed as follows:

and shall vex you in the land wherein ye dwell;
among other things by their wicked conversation, and by drawing them into sin through their ill examples, and so bring the displeasure of God upon them, and punishment for their evil doings.

Numbers 33:55 In-Context

53 And ye shall destroy all the inhabitants of the land, and ye shall dwell in it, for I have given their land to you for an inheritance.
54 And ye shall inherit their land according to your tribes; to the greater number ye shall give the larger possession, and to the smaller ye shall give the less possession; to whatsoever a man's name shall go forth , there shall be his : ye shall inherit according to the tribes of your families.
55 But if ye will not destroy the dwellers in the land from before you, then it shall come to pass that whomsoever of them ye shall leave shall be thorns in your eyes, and darts in your sides, and they shall be enemies to you on the land on which ye shall dwell;
56 and it shall come to pass that as I had determined to do to them, so I will do to you.
