'Today' in the Bible

"LORD God of Israel, there is no one like you, God of heaven and earth, who watches over his covenant, showing gracious love to your servants who live their lives in your presence with all their hearts. It is you, LORD God, who has kept your promise to my father, your servant David, that you made to him. Indeed, you made a commitment to my father David and then personally fulfilled what you had promised today.

But he sent messengers to him, who asked him, "What do we have in common, King of Judah? I am not here today opposing you. I am fighting the dynasty that is fighting me, and God has ordered me to hurry. For your own good, stop interfering with God, who is with me, and he won't destroy you!"
