A cruise through 1samuel chapter 21,22,23 and even 24 will expose how agents assigned to monitor David by his enemy trailed all his movement.If not for the anointing of God over his life he would have been swallowed up by enemy Saul.God is faithful he shows his servants steadfast love.
Lesson here is that we should be vigilant in flesh and spirit and becareful on who we relate with

1samuel 22vs6..When saul heard that david was discovered and the men that was with him
1samuel 23vs7..And it was told saul David was come to Keilah
1samuel 23vs13....And it was told Saul David was escape from Keilah
1samuel 23vs19...Ziphites came and told Saul where david was hiding
1samuel 24vs1..saying behold david is in the wilderness of Engedi

There was no man ever mention in the bible that the enemy monitored like David but God made him triumph over them all.

I prophesy to somebody that will say a loud Amen,Every monitoring agent assigned to monitor you in the flesh or in spirit that the God of David Open the grave for them In Jesus Name.
