the Berasit Hebrew Dictionary

משכ

'mesek' is traditionally interpreted rather inconsistently.

In only 36 instances, there are no less than 17 different interpretations, including; pull up, draw away, draw (pull back) a bow-string, pick out, deploy, extend, sow, follow, continue, prolong, postpone, defer, have patience, gratify, tall, the sound of a trumpet,

Other word built on this root include 'meseken' meaning “house” and 'mesekeb' meaning “bed”, so there seems to be a certain domesticity implied in 'mesek'.

With this in mind, consider again the meaning of “extend” and how that might apply to the homes of a nomadic culture.
