‘And as they were loosing the colt, its owners said to them, “Why do you loose the colt?” And they said, “The Lord has need of him”.'
Luke then tells us that the arrangements worked smoothly and were followed word for word. ‘Its owners.' This may possibly confirm that the ass was available for hiring out (along with other asses) so that the business was jointly owned.
“The Lord has need of him.” This has been repeated twice for emphasis, underlying the importance that Luke sees in it. The One Who is Lord of all is exercising His authority.
