'Reward' in the Bible

Moreover, your servant [is] warned by them; in keeping them [is] great reward.

And people will say, "Surely [there is] a {reward} for the righteous. Surely there is a God [who] judges in the land."

My flesh and heart failed, [but] God [is] the {strength} of my heart and my reward forever.

Look, children [are] the heritage of Yahweh; the fruit of the womb [is] a reward.
