The motif of God making the barren fertile in response to their trust and obedience runs through the rest of 1 and 2 Samuel (cf. Samuel). So does the corollary truth that God will make the "powerful," who are not trusting and obedient, infertile and ultimately dead (cf. Saul). Likewise the motif of the Lord’s anointed king is a major one in 1 and 2 Samuel (cf. David). Thus this prayer prepares the reader for the rest of the book.
