Like Moses, Jesus went up on a mountain to give his law to Israel.
Now [when Jesus] saw the crowds, he went up the mountain and [after he] sat down, his disciples approached him. And opening his mouth he began to teach them, saying, Matthew 5:1-2
And then it went like this:
“You have heard that it was said to the people of old [by Moses], ‘Do not murder’, but I say to you ..."
The 4th commandment was meant to cause Israel to cease for one day from laboring for the things of this world so that they might know GOD. IMO these verses are where Jesus essentially said, “You have heard that it was said to the people of old [by Moses], ‘Keep the sabbath holy', but I say to you..."
“No one is able to serve two masters. For either he will hate the one and love the other, or he will be devoted to one and despise the other. You are not able to serve God and money.
“For this [reason] I say to you, do not be anxious for your life, what you will eat or what you will drink, and not for your body, what you will wear. Is your life not more than food and your body [more than] clothing? Consider the birds of the sky, that they do not sow or reap or gather [produce] into barns, and your heavenly Father feeds them. Are you not worth more than they [are]?
And who among you, [by] being anxious, is able to add one hour to his life span?
And why are you anxious about clothing? Observe the lilies of the field, how they grow: they do not toil or spin, but I say to you that not even Solomon in all his glory was dressed like one of these. But if God dresses the grass of the field in this way, [although it] is [here] today and tomorrow is thrown into the oven, will he not [do so] much more [for] you, you of little faith?
Therefore do not be anxious, saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear?,’ for the pagans seek after all these [things]. For your heavenly Father knows that you need all these [things]. But seek first the kingdom of God and his righteousness, and all these [things] will be added to you. Therefore do not be anxious for tomorrow, because tomorrow will be anxious for itself. Each day has enough trouble of its own. Matthew 6:24-34
Seek first the kingdom of God and his righteousness. This correlates well with the 4th element of the lord's prayer
Therefore you pray in this way: “Our Father (1) who is in heaven (2), may your name be treated as holy (3). May your kingdom come, may your will be done on earth as [it is] in heaven (4). Give us today our daily bread, and forgive us our debts, as we also have forgiven our debtors. And do not bring us into temptation, but deliver us from the evil one. Matthew 6:9-13
