Do Not Kill Your Children From Fear of Poverty

Twice God tells us in the Quran not to kill our children due to fear of poverty 17:31 and 6:151, but there is a slight difference to how God assures the believers in these two verses.

In 17:31 it says God provides “for them and for you” while in 6:151 God informs us that He provides “for you and for them.” Why the difference?

It is interesting to note that the word for “fear” in Arabic “خَشْيَةَ” only appears in 17:31 (them & you) and not in 6:151 (you & them). I believe there is a particular reason for this.
