'Yourself' in the Bible

Then he said to her, "Go, ask for yourself [some] containers from the streets, from all your neighbors. {You must collect as many empty containers as you can}!

Then he said, "Pick [it] up for yourself," so he stretched out his hand and took it.

How {can you repulse a single captain among the least of the servants of my master}? [Yet] you rely for yourself on Egypt for chariots and horsemen!

because you have a responsive heart, and you humbled yourself before Yahweh when you heard how I spoke against this place and against its inhabitants to become a desolation and a curse, and you have torn your clothes and wept before my face, I have also heard, declares Yahweh.
