'Generations' in the Bible

[So] know that Yahweh your God, he [is] God, the trustworthy God, maintaining his covenant and his loyal love with those who love him and with those who keep his commandments to a thousand generations,

"You shall not move the boundary [marker] of your neighbor that {former generations} set up on your property in the land that Yahweh your God [is] giving to you to take possession of it.
