The angel's announcement of John's birth occurred even before Elizabeth conceived him (cf. Matt. 1:18-25). This is further evidence of his being a special provision from the Lord. Elizabeth's self-imposed five-month period of seclusion may have been to safeguard the arrival of her child and her own health as an older woman. Elizabeth gratefully acknowledged God's grace in removing the disgrace of her childless condition (cf. Gen. 30:23; Ps. 113:9).

"Elizabeth pictures the righteous saint who takes her burden to God and rejoices when that burden is lifted."42
