Psalm 24:1-6 and Isaiah 7:10-14

Psalm 24:1-6
A psalm of David.
The earth is the LORD’s and all it holds,
the world and those who dwell in it.
For he founded it on the seas,
established it over the rivers.
Who may go up the mountain of the LORD?
Who can stand in his holy place?
“The clean of hand and pure of heart,
who has not given his soul to useless things,
what is vain.
He will receive blessings from the LORD,
and justice from his saving God.
Such is the generation that seeks him,
that seeks the face of the God of Jacob.”

Isaiah 7:10-14
The LORD spoke to Ahaz, saying: 
Ask for a sign from the LORD, your God; 
let it be deep as the netherworld, or high as the sky!
But Ahaz answered,
“I will not ask! I will not tempt the LORD!”
Then Isaiah said:
Listen, O house of David!
Is it not enough for you to weary people, 
must you also weary my God?
Therefore the Lord himself will give you this sign: 
the virgin shall conceive, and bear a son, 
and shall name him Emmanuel.
