Minecraft: Pickaxe?

Me on Minecraft PE version, is it a player in the PE, e.g. Give a diamond pickaxe with infinity by command, or is there another way to make the pickaxe as good as indestructible?

If you have Halbarkeit 3 on it will hardly ever break.

I WAS IT: I have a picke (diamond) the efficiency IV, Durable III, luck III and repair I have… (I also play minecraft pe… So on mobile…) and command? Ne… But durability III and repair I is most insisted parts because durability ensures that it is 1x, 2x or 3x so long bar is… And repair causes as soon as you z.b. Lapis / redstone / coal / dias build their xp on the durability of the tool go what you hold in your hand what with enchantment I enchanted is and if you repair it with ambos need always the same amount of xp without enchantment more and more to repair…

Enchantments but already… So more xp… Because it has nothing to repair with tuhn… LG

1) why not… Thanks for that and 2) it's really harder to find repair than any other enchantment… Hope you know what I mean…
