'Perhaps' in the Bible

And [while] the people were waiting expectantly and all were pondering in their hearts concerning John, whether perhaps he might be the Christ,

But he said to them, "You give them [something] to eat!" And they said, "{We have no} more than five loaves and two fish, unless perhaps we go [and] purchase food for all these people."

So the owner of the vineyard said, 'What should I do? I will send my beloved son; perhaps they will respect him.'
