Exodus 20:17

17. "You shall not covet your neighbor's house. You shall not covet your neighbor's wife, or his manservant or maidservant, his ox or donkey, or anything that belongs to your neighbor."

Selected Passages from Ecclesiastes 

And I saw that all labor and all achievement spring from a man's envy of his neighbor. This too is meaningless, a chasing after the wind.

Whoever loves money never has money enough; whoever loves wealth is never satisfied with his income. This too is meaningless. As goods increase so do those who consume them.

I undertook great projects. I built houses for myself and planted vineyards. I made gardens and parks and planted all kinds of fruit trees in them. I made reservoirs to water groves of flourishing trees...I also owned more herds and flocks than anyone else in Jerusalem . I amassed silver and gold for myself...I denied myself nothing my eyes desired. I refused myself no pleasure. My heart took delight in all my work and this was the reward for my labor. Yet when I surveyed all that my hands had done...everything was meaningless, a chasing after the wind.

Moreover, when God gives any man wealth, and possessions, and enables him to enjoy them, to accept his lot and be happy in his work, this is a gift of God.

Do not say, "Why were the old days better than these?" For it is not wise to ask such questions.

John 6:35

35. Then Jesus declared, "I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty.
