'Perhaps' in the Bible

Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control.

The seed you sow is not the body (the plant) which it is going to become, but it is a bare seed, perhaps of wheat or some other grain.

but it may be that I will stay with you [for a while], or even spend the winter, so that you may send me on my way to wherever I may go afterward.
