Mark 4:23-25 (ESV)

²³ If anyone has ears to hear, let him hear.” ²⁴ And he said to them, “Pay attention to what you hear: with the measure you use, it will be measured to you, and still more will be added to you. ²⁵ For to the one who has, more will be given, and from the one who has not, even what he has will be taken away.”
