Give portions to seven, yes, to eight, for you do not know what disaster may come upon the land.
Unforeseen downturns & economic pressures are a fact of life and we can adopt various schemes to mitigate their effects.
One such scheme is to save for that 'rainy day'. The challenge is figuring out quite how much to save, as enough never seems to be enough when it comes to covering all our bases.
Jesus picked up on another approach in the parable of the shrewd manager (Luke 16). The manager was commended for wisely using money to win future favour with people (after he had lost his job).
Solomon's approach is 'be generous whilst you can'. The heart of this is more than just a pragmatic 'win friends whilst you can', it must be a trust in God's economy. God is able to respond to our faith filled generosity by meeting our needs through those we have helped. This is true equality & economic community, the 'haves' meeting the needs of the 'have-nots'.
2Cor8v14 Your plenty will supply whay they need, so that in turn their plenty will supply what you need.
