'Fulfillment' in the Bible

"{When you make a vow} to Yahweh your God, you shall not postpone {fulfillment of it}, [for] certainly Yahweh your God shall require it from you and [if postponed] {you will incur guilt}.

And blessed [is] she who believed that [there] will be a fulfillment to what was spoken to her from the Lord!"

Love does not commit evil against a neighbor. Therefore love [is the] fulfillment of the law.
