פירוש רש״י
מסת נדבת ידך means sufficient (די) free-will offerings of thy hand (i.e. of thy possession) (cf. Targum on Deuteronomy 15:8, which renders די מחסרו by כמסת חסרונה); everything must be in accordance with the blessing which God has bestowed upon you (אשר יברכך): offer peace-offerings of rejoicing and invite guests for the meal.
