'Heed' in the Bible

so that the Lord may fulfill His promise concerning me, saying, ‘If your sons are careful regarding their way [of life], to walk before Me in truth with all their heart and mind and with all their soul, you shall not fail to have a man (descendant) on the throne of Israel.’

Now therefore, O Lord, the God of Israel, keep for Your servant my father David that which You promised him when You said, ‘You shall not be without a man (descendant) to sit on the throne of Israel, if only your sons take heed to their way [of life] to walk before Me [according to my laws] as you have done.’

So when all [the ten northern tribes of] Israel saw that the king did not listen to them, the people replied to the king, saying,“What portion do we have in David?We have no inheritance in the son of Jesse;To your tents, O Israel!Look now after your own house, David!” Then Israel went back to their tents.

All the elders and all the people said to him, “Do not listen or consent [to this additional demand].”
