What does this Shakespeare line mean, from Hamlet?

Question

What wouldt thou beg Laertes,

That shall not be my offer, not they asking?

is CLAUDIUS dissing LAERTES, i don't understand

the notes translate "not thy asking" to "rather than thy asking" but that doesn't tell me what the rest of it means

Answer 1

"what wouldst thou beg, Laertes, That shall not be my offer, not thy asking"

What is it you want, Laertes, would I not offer it to you before you even asked for it, if I only knew what it was?

Far from dissing him, he's assuring Laertes he enjoys royal favor, and can ask whatever he wants.
