You may remember that near the start of Exodus we read a lot about Pharaoh having a hard heart, but now as we approach the end of the book we read of some better types of heart. You won't spot this unless you are using a very literal Bible translation (such as the old King James Version), but this chapter mentions the word heart nine times:

v.5 - whoever has a willing heart
v.10 - whoever has a wise heart
v.21 - whoever's heart is moved
v.22 - whoever had a willing heart
v.25 - whoever had a wise heart
v.26 - whoever's heart was moved
v.29 - whoever's heart made them willing
v.34 - who each had a heart to teach
v.35 - whose hearts were filled with wisdom

Questions to ponder: What sort of heart do you have towards God? A generous and committed heart - like the people in this chapter? A hard heart - like Pharaoh? A gentle and gracious heart like that of the Lord Jesus who made his way to the cross for your sake?

Create in me a pure heart, O God,
and renew a steadfast spirit within me ...
My sacrifice, O God, is a broken spirit;
a broken and contrite heart you, God, will not despise

(Psalm 51:10,17)
