Samuel was a prophet who had favor with God and he sought the face of God before taking most decision. Saul was a King who was anointed of God by Prophet Samuel before he lost it through disobedience. At the beginning the Spirit of the Lord came upon Saul and He prophesied according to the words of Samuel.
There were some missing donkeys which Saul and his servants set out to look for. Before they set out, Samuel told them plainly that the donkeys have been found. An inquisitive uncle asked Saul about what Samuel said and Saul gave a partial disclosure.
Verse 16 in particular reads “So Saul said to his uncle, “He told us plainly that the donkeys have been found.” But about the matter of the kingdom, he did not tell him what Samuel had said.”(NKJV)
This is a study in wisdom and discretion in disclosure. There are times we have to exercise discretion in what we tell others. Without necessarily telling lies, we have to know how to keep secrets, especially from known or potential enemies. This serves as a check against jealousy or envy that the enemy will use to truncate the plans and purpose of God for our lives. We must know what and how to disclose and what to keep as temporary secrets.
