Strength gets delivered wherever a person is wholly aimed, which is why a hedging heart feels underpowered everywhere.
A whole heart is an aim before it is a virtue, and the roving eyes of Yahweh are a supply line that runs to whatever the aim points at. Divided attention does not halve the result, it forfeits it, because a man facing two directions arrives at neither with his full weight behind him.
A man who once stood in front of an impossible army with nothing but reliance later bought an alliance with temple silver, and the wars that follow are less a penalty than the standing condition of a man who now solves things by hedging. Once purchase becomes the answer, every new threat requires another one. Hedging costs a person the certainty it was bought to protect.
