God's word will be realized. So Elizabeth becomes the next one to encounter his work. The text simply notes this fulfillment by mentioning that she became pregnant. There is no fanfare, just a simple declaration that what the angel had promised in verses 13-17 comes to pass. For some time Elizabeth remained in seclusion. Her withdrawal has no stated motive, though many have speculated on her reasons. What we do know is that she praised God for what he was doing through her. Her disgrace, the reproach of barrenness, was gone. Such thankfulness for the arrival of a child was common (as in Gen 21:6; 30:23). Joy and relief are mixed together in Elizabeth. She appears to be preparing herself for what is ahead. God is powerfully at work again for Israel and for this righteous couple, who are learning anew what it is to trust God. When God speaks and acts, people are supposed to listen. His word will come to pass.
