Colloquially hate seems to be used as: to be the enemy of, to oppose, to find contemptible. Stuff like that.
That use is used within the Bible (for example we are to hate evil), but the Bible also uses hate as a relative level of love:
For example Genesis 29:30-31 (ESV):
30 So Jacob went in to Rachel also, and he loved Rachel more than Leah, and served Laban for another seven years.
31 When the Lord saw that Leah was hated, he opened her womb, but Rachel was barren.
This translation makes it clear (and seems closer to the underlying words used) in this particular instance compared to other translations.
The love vs hate in this case is a matter of degree. This also seems to apply with "Jacob I have loved, Esau I have hated." as well as when Jesus uses it (Luke 14:26 ESTV):
If anyone comes to me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple.
This is clearly a matter of degree of love, not a call to despise our parents.
[Edit - below this point]
The parallel passage of this in Matthew reiterates the matter of degree of love interpretation (Mt 10:37 ESV):
Whoever loves father or mother more than me is not worthy of me, and whoever loves son or daughter more than me is not worthy of me.
