speckled vs. spotted

What is the difference between speckled and spotted in the following context:

I will pass through all thy flock to day, removing from thence all the
speckled and spotted cattle, and all the brown cattle among the sheep,
and the spotted and speckled among the goats: and of such shall be my
hire. – Gen. 30:32 AV

I did research in a few dictionaries and yet can not grasp the distinction between the two.
For example, W3 provides the following definition for speckled

: covered or marked with speckles : spotted

SOED states the following:

Covered or marked with (numerous) speckles; variegated or flecked with
spots of a contrasting colour

Not too much help comes from OED:

Covered, dotted, or marked with (numerous) speckles or specks;
variegated or flecked with spots of a different colour from that of
the main body; spotted

For a non-native speaker, these definitions don’t provide a clear distinction between the two words, they seem to be synonymous.
