This week’s Haftara encourages us to test God: Bring the full tithe…and thus put Me to the test – said the LORD…I will pour down blessings on you. In other words, we should give charity and expect blessing in return. But another verse teaches us Do not test the Lord – can we reconcile these verses? The Malbim explains that there two types of tests – one assesses that which we do not know – and in this regard we were warned against testing God. Another type only affirms that which we already know. We know that God is the source of all blessing and that God wants us to give charity, Thus, this test only proves that which we already know and in this regard the Prophet encourages us to test God.
